Eva and her two brothers spend a few days at her grandfather's house, where she finds a very special device that allows her to travel in time.

Eva and Rubén appear in the middle of the biggest TV show in 1957: Club 57. Eva meets a cute boy who is willing to help her.

Eva and Rubén hatch a plan, but first they must find more appropriate clothes for 1957. JJ is determined to end his secret relationship with Vero.

Although he thinks they are crazy, Manuel decides to help Eva and Rubén in exchange for a favor: that they help him get closer to Amelia.

The Rosagatas hear Miguel and a program executive talk about a new star and believe it is Vero. They couldn't be more wrong...

Manuel still can't believe that Eva and Rubén time traveled, so Rubén decides to show him his cell phone, triggering an alarm at the Time Center.

Vero and the Rosagatas look for Eva. JJ also wants to find Eva to apologize and invite her to his house. The guardians of time are still on the prowl.

Aurek arrives at Manuel's house in search of Eva and Rubén, but his mission is interrupted. Amelia and Manuel argue over a misunderstanding.

Vero and Eva ask JJ for an explanation when they realize he is playing with them. In the Time Center, Diana discovers that Manuel is lost in Italy.

Diana notices that Martin reappears in the photos. Calmer now, he returns to the Center, determined to get rid of Aurek.

After JJ's departure, Eva listens to the song he left on the jukebox. She accepts that it would be best to return to the present.

JJ's father receives him in Italy with a surprise party. Eva warns Rubén that they will be trapped in 1957 if they fail to charge the cell phone.

After the failed call with JJ, Eva wants to travel to Italy. Rubén agrees to play basketball with Checho and Oso and becomes one of the Falcones.

JJ is very happy to see Eva in Italy but does not understand how she arrived so fast. Aurek returns the CUCI at the right time but in the wrong place.

A guardian of time appears in Italy to capture Eva. Manuel learns that Eva is in Italy and worries about her and the timeline.

Eva returns to her time and discovers that altering the timeline changed their lives radically. Rubén is enjoying this new reality to the fullest.

JJ wants to write a letter to Eva but doesn't know which address to send it to. Rubén will do anything to prevent the restaurant demolition.

Rubén finds a comic from the past and Eva finds a very important letter. Vero talks to JJ but interference on the line generates a lot of confusion.

Miguel sends a telegram to JJ to invite him to sing in Club 57 with Jessica Renata. Meanwhile, in 2019, Rubén organizes a big party.

JJ learns that Vero went looking for him in Italy and that Eva never returned from there. Rubén refuses to return to 1957 to correct the timeline.

While Rubén continues with his plan to have a party at the restaurant, Eva convinces him to look for the FrankenTV and return the timeline to normal.

After discovering JJ returned from Italy, Eva is more convinced to return to 1957. Vero believes he can recover JJ. Manuel tests the time machine.

Rubén falls apart when he sees that the Nono did not keep his word and decides to help Eva find the time machine. The Lady also joins the search.

Aurek and Droide confirm that they should erase what JJ wrote so Eva doesn't read it. Diana and Victor plan to use FrankenTV to return to the Center.

In 2019, Eva visits Mercedes, who confirms that nobody knows what happened to JJ. Meanwhile, in 1957, Blackbeard arrives at school looking for Aurek.
