John Dorian, "J.D." to friends, is a boyishly handsome, self-deprecatingly funny, likeable guy who would be confident if he only realized his assets. Four years of medical school have prepared J.D. for his first day as an intern at Sacred Heart Hospital - but he has his doubts.

J.D. tries to persuade a smoker patient to quit smoking in order to impress Dr. Cox, who is just feeling lonely in his opinion. Elliot's attitude towards Carla annoys her, thus Turk is able to go on a date with Carla, when he convinces her to forgive Elliot.

J.D. begins to feel distant from Turk, when he leaves him abandoned every time that he tries to talk to him. Elliot fights with Kelso for calling her "sweetheart," and she seeks Dr. Cox's advice. J.D.'s relationship with Elliot goes in a time race, when he has 48 hours to kiss her before he is put into her "Friend Zone."

The three interns are each assigned patients with various illnesses. Statistically speaking, one of the three is going to die. J.D.'s patient is 86 year old Mrs. Tanner, who is in renal failure. 20 year old David Morrison is Turk's hernia patient and Elliot's patient Mrs. Guerrero only speaks Spanish and might have lupus.

J.D. points out what seems to be a technical mistake to Dr. Kelso, but it was really an attempt of Dr. Cox to save a woman without insurance using a dead guy's insurance. Dr. Kelso and Dr. Cox show J.D. their different ways of looking at medicine. Meanwhile, the Janitor intimidates J.D., Elliot discovers the healing powers of her boobs and Turk gives Carla a pen he thought he took from the Lost and Found box.

Dr. Cox is still facing the threat of suspension, and coincidentally, J.D. is assigned to a special patient: Jordan Sullivan, an important board member. She is very demanding and J.D. ends up sleeping with her after he confronts her. Only he didn't know that she is Dr. Cox's ex-wife, and now the only one who can save J.D.'s mentor from being fired by the evil Dr. Kelso. Meanwhile, Elliot is assigned to take care of a shrink whose jaw has been wired shut, and for whom she ends up becoming a patient. Carla's mom makes a scandal after Turk spends the night at Carla's, and when she breaks her leg, Carla blames Turk for it.

J.D. has finally earned the spot as brightest student, but he's got competition: Nick Murdoch, who seems to be nicer, friendlier and has a better butt than him. But even J.D. can't hate the guy, for he is so nice. But he is surprised when he finds Nick sitting in a corner crying because he can't take the pressure of medical internship. Meanwhile, Turk is having problems at the operation table and doesn't tell Carla, who keeps bothering Dr. Cox about it. And Dr. Cox gives Turk a very unique suggestion on how to calm down before surgery.

J.D. and Turk become heroes after saving a cameraman's life on TV, while heading to a strip club. But Turk quickly becomes the target of a new publicity campaign led by Dr. Kelso, exploiting the hospital's diversity. Meanwhile, J.D. worries about his evaluation. Elliot is going out with Carla, but in the last minute she blows her off and later Elliot runs into her in a bar.

J.D. gets to see the hospital through the eyes of a patient when he's admitted for appendicitis. Elliot examines him and he tells everyone how cold and rough she is, which drives her crazy. J.D. doesn't want Turk to operate on him, which hurts Turk's feelings. Meanwhile, Dr. Cox is trying to show off to his mentor, Dr. Benson, the ex-chief of medicine, who is also a patient at the hospital. The only thing in his way is Dr. Kelso, who almost dismissed Dr. Benson prematurely.

J.D. begins a new relationship with Carla. J.D. gains a new nickname - "Scooter" - and his relationship with Nurse Carla evolves as he begins to out-distance her medical knowledge, while Turk trembles, when he learns that his secret lunch spot was claimed years ago by the territorial Dr. Kelso. Elsewhere, Dr. Cox gives Elliot the evil eye when she won't discharge a troublesome patient.

It's Christmas, and even though J.D. and the others don't really feel like celebrating, Turk makes a huge deal about it. But his faith and happiness are gone after a very busy night at the hospital. Dr. Cox has J.D. videotape the birth of the child of one of his friends.

A woman slips and falls on the wet floor of the hospital. Afraid that she might sue the hospital, Dr. Kelso asks J.D. to stand by her and be friendly, so she won't sue them. But J.D. is very busy with Dr. Cox's 24-hour marathon to keep his ICU patients alive. Elliot is desperate for some attention from Dr. Cox. Meanwhile, Turk snaps at Carla when she steals fries from his plate.

J.D. is frustrated when his budding romance with an ex-patient wilts as their dates are constantly interrupted by emergency calls, while the beastly Dr. Kelso becomes less fearsome to the wide-eyed interns, when Dr. Cox informs them how to avoid the blowhard's bite. In addition, a perplexed Carla and Turk deal with their first sexual intimacy complication.

Alex and Elliot argue over missing medication, and J.D. needs to choose sides. Meanwhile, Dr. Kelso gives Carla a ride to work and she sees a totally different side of him. Turk develops a conflict with Dr. Cox after he finds out that Dr. Cox has secret feelings for Carla.

After going to bed and spending an entire day having sex, J.D. and Elliot go to work trying to hide their new secret romance, but everybody already knows it.

When a rampaging Dr. Cox suddenly shows up at his door in a strange funk, J.D. sees a possibility of a breakthrough in their relationship - until he learns that Cox loses control in almost an annual rite. Meanwhile, Turk elects to partner with Elliot on a research project so that he can maneuver her back with his buddy J.D., and Carla struggles to fulfill a comatose patient's final request - playing heavy metal music in his room.

J.D., Elliot and Turk are receiving their first medical students, and now they finally get a chance to see what it feels like to be on the other side. Turk's student is a very attractive young woman, to whom Dr. Cox is immediately attracted. But he doesn't know his way around women and needs Turk to give him a little help. J.D. doesn't know how to handle his student and Elliot's turns out to the be son of an important CEO.

J.D. has a patient who's rude to him and the nurses and eventually dies from cancer. J.D. feels awful for not giving him his full attention and worries maybe he could have saved the guy if he was nicer to him. Meanwhile, Elliot is convinced that Dr. Kelso is the one singing a song called "Tuscaloosa Heart" on a tape given to her by a patient who claims he went to college with Bob. And Dr. Cox finds himself trapped in a love square: He's falling in love with Kristen Murphy, his intern, just as his ex-wife reappears demanding sex – and there's also his crush on Carla.

An assortment of moms and dads descend on their offspring at home and in the workplace. J.D.'s father is a gregarious yet lonely divorcee who's desperately trying to be just one of the guys. Elliot's folks, on the other hand, are a snooty couple whose pompous behavior dismays their daughter. Similarly rattled is Turk, unnerved by the bonding of his girlfriend, Carla, and his brassy mother. But the most vexatious parent by far is the janitor's dad.

Turk's competitiveness is starting to annoy J.D., especially when it crosses the line of personal jokes and comes to patient's matters. Meanwhile, Dr. Cox finally has a taste of good coffee, but thanks to his feud with Dr. Kelso, the only nurse who was able to make it gets fired. Elliot meets a very attractive patient, whom she instantly identifies, but has a really hard time getting him to ask her out.

J.D. fears being contaminated with Hepatitis B, after a needle accidentally sticks his forearm. Meanwhile, Elliot has a hard time combining her new relationship and keeping up with studies. Turk obsesses about getting in shape, after Carla makes a fat joke about him.

Jordan's brother Ben is admitted at Sacred Heart for having an accident with a nail gun. J.D. learns that Ben has leukemia, but won't believe it, since there have been many mixups in the hospital lately, so he goes on a search for the real test results.

Ben takes the news of his diagnosis pretty well - at least better than his sister Jordan and J.D. Remarkably, it is Dr. Cox who is the voice of reason and compassion, until his own fears get in the way. Meanwhile, Turk and Elliot have their own issues to deal with. Turk is upset because he wasn't chosen to assist on a difficult surgery and Elliot is criticized during rounds by Dr. Kelso for the 100th time.

It's J.D.'s last day as an intern, and soon he will become a resident. Carla and Turk are arguing about dating other people. Elliot finally rebels against being everyone's doormat, and J.D. is just trying to stay out of people's way. Jordan has returned to get a physical and a new patient, Mr. Bober, has been admitted, because he needs his gall bladder removed. He really needs the surgery, but doesn't have the insurance to pay for it. They enlist the help of Dr. Cox, Dr. Wen and Jordan.

Relationships between the staff of Sacred Heart Hospital have been shaken since Jordan's revelations. Turk is sleeping on J.D.'s bed, after Carla kicked him out of his own. Elliot is having a hard time facing J.D. every day at work. J.D. desperately tries to get Dr. Cox's attention back, unsuccessfully.

J.D., Elliot and Turk find themselves alone in the hospital night shift and face responsibilities without supervision for the first time. Luckily, they have Carla there to support and guide them through the night. Meanwhile, Dr. Cox doesn't know what to do, when he realizes that he has feelings for his ex-wife Jordan and is asked (forced actually) to introduce Dr. Kelso at a social event, where he will be receiving an award from the medical board.

When Dr. Kelso challenges the residents by offering a trip to a medical conference in Reno as a reward to the individual, who presents the most interesting case study, J.D. refuses to play along, earning him the respect of Dr. Cox. In the meantime, Turk misses his opportunity to ask for a new laser on the one day of the year, that Dr. Kelso grants favors, so he is forced to find another way to come up with the goods.

J.D. insists that Carla should open up to him. When she finally starts to do that, J.D. screws it up by telling Turk. Elliot is desperate for attention from Dr. Cox. Turk sees himself in an ethical dilemma when Dr. Kelso picks him over a female surgeon to spend a weekend in Mexico.

Elliot sleeps with a handsome doctor she hardly knew and soon becomes the hospital tramp. Turk suffers from his back after operating with Dr. Amato, a very short surgeon. J.D. finds out that wearing a white coat doesn't make him a better doctor, but is upset by having Dr. Cox throw in his face that he made another mistake. And Dr. Kelso is just dying for an opportunity to lash out his anger on Dr. Cox.

J.D.'s brother is in town. Turk is thrown out of a patient's funeral for not knowing his name and feels even worse because earlier he made a bet with Dr. Cox over another patient's life.

All of the male doctors are euphoric due to the visit of Julie Keaton, the pharmaceutical sales rep, except for Dr. Cox, who still believes in treating patients for their best health, instead of trying to get some attention from the hot Ms. Keaton. Meanwhile, J.D. and Elliot argue over a risky decision regarding one of Elliot's patients. Turk tries to talk Carla into entering a practitioner nurse course, so she won't be so underestimated by the doctor's staff.

When an expectant Jordan shows up unexpectedly, Cox is forced to choose between her and his new love, Julie. Meanwhile, J.D. and Turk take advantage of the hospital's supply closet for sleep, when they take on extra shifts at a free clinic to supplement their income. Carla encourages Elliot to stand up to her father, when he pressures her to pick a specialty more "suitable for a woman."

Ever since her father cut her off financially, Elliot's been feeling the weight of the world on her back. While having to find a new affordable place to live, she also has to face the threat of being sued by a patient whom she told he had only eight months to live. Carla and Jordan hit a sore spot when Carla gives her opinion on Jordan and Perry's relationship. Meanwhile, J.D. has a fight with Dr. Cox and the two dispute over who gets to give the better treatment to two patients with the same prognosis.

Elliot still doesn't have a place to live. J.D. think he's lost his mojo when he can't even kiss the giftshop girl while they go out on a date. Turk and Carla are having romance problems, because she feels he's not being as generous to her as she is to him. And Dr. Cox freaks out when he lets Jordan move in to his place due to her pregnancy.

Renewed sex with J.D. calms Elliot, who's facing personal and professional dilemmas: She's broke, and patients are bailing out on her.

Comeuppances are in store for Dr. Cox, Dr. Kelso and J.D. from a hypochondriac, a surgical patient and Elliot, who wants more than just sex from J.D.

J.D. bonds with a patient, who is waiting for a heart transplant and discusses with her their idea of what death must be like. Elliot puts her foot down and demands a feminine locker room from Dr. Kelso. Turk decides it's time to propose to Carla, but a kid swallows the engagement ring.

Turk is still waiting for Carla to answer his proposal and asks his brother to stay over a few days to help him deal with it. Dr. Townshend, an old friend of Dr. Kelso and one of the nicest doctors around befriends J.D. Elliot accidentally finds out the sex of Jordan's baby, becoming the object of Dr. Cox's anxiety.

Elliot meets a nice guy at the bar, but freaks out when she finds out he's a male nurse at Sacred Heart. Turk keeps asking Carla to marry him, but she still won't give an answer. Dr. Cox feels the pressure he puts on himself everyday: His psychiatrist, his subordination to Dr. Kelso and his paternal feelings for J.D.

J.D. and Turk think they've got bad karma after hitting a car and causing an accident, while playing golf on the hospital roof. Dr. Cox bends over backwards to give Jordan as much comfort as possible on her labor day, and she confesses to J.D. that Dr. Cox is the real father. Elliot seeks advice from Carla on how to tell Paul that she's crazy, because they're getting more intimate and she can't hide it anymore. But Carla is feeling too crazy herself with the upcoming wedding.

A personal secret of Dr. Cox is revealed during hospital visitations by a cocky MD (Jay Mohr), who establishes a rapport with J.D.

J.D. flirts with the wife of a patient who's been in a coma for the past two years, whom they all call T.C.W. (Tasty Coma Wife). He feels guilty for doing that, even though she wants to go ahead with it. Meanwhile, he can't stand listening to any more relationship problems, as everybody dumps their issues on his ears: Elliot, sabotaging her relationship with Paul over beef jerky, Carla, finding out her engagement ring passed through a patient's digestive system and Dr. Cox's unsucessful attempts to get some attention from Jordan, who can only think about her baby right now.

Turk takes J.D. up to surgery, and right from the start J.D. steps all over Turk when trying not to be the geek among the surgeons. Paul hears Elliot say "I love U2" while she was rearranging her CDs and thinks she said "I love you too." Dr. Cox decides to get even with Dr. Kelso by telling everyone he's dead, revealing what people really think of him.

Jamie's (T.C.W.) husband died, and J.D. struggles with the ethical issues involved in starting a relationship with her. Dr. Cox babysits his son, whom Jordan still hasn't chosen a name for, and is disturbed that he feels nothing for the baby. Turk is haunted by erotic dreams about Elliot, which gets him into hot water with Carla.

J.D. carries on with his romance with Jamie, but finds himself at a dead end after realizing she's a drama queen. Dr. Kelso makes Dr. Cox give a class on how to approach the patients nicely in order to prevent possible law suits. Carla's mother dies and she wants to get married.

J.D. and Turk's college buddy, Spence, drops by for a visit, and accidentally tells Dr. Cox a secret. Too much partying with successful Spence causes Turk and J.D. to show up late and drunk for work, which Dr. Kelso fully reprehends them for. Elliot's feeling low since she can't measure up to Dr. Kelso's standards, and the Janitor starts another feud – this time over paychecks – with J.D.

A run-in with her old flame Sean and an accident in her new car lead Elliot to the realization that nothing good has happened to her in the three years that she has been at Sacred Heart. This realization drives her to take drastic measures, including a complete makeover, both inside and out, in an attempt to change her luck. Meanwhile, J.D. gets stuck with a patient, whose diagnosis he can't quite pin down, and when Dr. Cox denies him any assistance, he looks to Carla and Turk to help him out. While Dr. Cox is busy not helping J.D., he takes the time to make amends with Dr. Kelso.

J.D. is feeling left out of his friendship with Turk and gets hurt when Turk is scared of opening up to him. Meanwhile, Carla is driven crazy over an unidentified urine sample, and Elliot tries to balance Sean and her career, so that one doesn't end up getting in the way of the other.

Finding difficulties training his interns, J.D. asks to Elliot for some help. She tells J.D. about Sean, who gave Elliot great tips based on his dolphin training that fit perfectly for her interns. Dr. Cox finds the ideal pediatrician for his son: Dr. Norris, who acts and looks just like him. However, Dr. Cox is quick to find a problem with him once Jack develops a cough that scares both him and Jordan.

Sean is a bit surprised and disturbed to learn about Elliot and J.D.'s history together, but it turns out his anger is really a cover up for his upcoming six month long trip and he doesn't want Elliot to explode. Dr. Cox. is forced to swallow his pride and actually ask for help when he decides to throw his hat in the ring for the Residency Director position at the hospital. Carla picks up an extra shift as a surgical nurse, which allows her to spend the day working alongside with Turk, to his great annoyance.

Dan decides to stay with J.D. for a while after their mom's new fiancé kicks him out, but after spending some quality time with him at the hospital, Dan isn't sure if he likes the cynical person his little brother has become. Elliot tries to deal with her own problems of a long distance relationship and decides to try moonlighting as a pet examiner with Carla to save up money.

A chance meeting in the elevator sparks a new friendship between J.D. and the mysterious Danni whose ongoing dialogue about her ex forces J.D. to talk about his feelings for Elliot. Carla's brother Marco comes to visit, but he still hasn't forgiven Turk for mistaking him for a valet at their mother's funeral. Unfortunately, Turk can't even apologize because Marco can't speak anything but Spanish. At the hospital, Dr. Cox relishes his new job promotion but is surprised when J.D. doesn't follow his lead in contradicting Dr. Kelso's orders.

As J.D.'s relationship with Danni progresses, he and Dr. Cox are forced to spend more time together outside of the hospital, to Perry's great chagrin.
