The series revolves around a girl named Lea who accidentally stumbles upon a corpse during a party and wakes up the next day thirty years in the past. Then, she starts swapping bodies with other people. Each time she does this, she gets to know more about the people who are close to her. Lea learns that many secrets are embedded in the sands of time and that it is important to walk a mile in someone else’s shoes before criticizing them.

The first person that she wakes up in is the high school boy Ismael, whose skeleton hand she found. She finds out that he was a promising candidate for BRIM, the premier music school. However, he was rejected by Karine because of his drug problems. Lea also knows that Ismael’s father had an affair with his wife and this might have been one of the reasons for Ismael’s death.

Then she moves to the body of Patricia who is an old friend of Ismael’s mother. In the past, she was the victim of domestic abuse and she killed her husband in self-defense. She tries to convince Lea that she did not kill Ismael and that she just shot him in the head. Lea also gets to know that Pye was the real murderer of Ismael’s brother, Soufiane. Lea then tries to save Ismael’s son from getting an abortion. Throughout the episode, Lea continues to swap between different bodies as she tries to find out how Ismael died. The show is a binge-worthy one and Khalil Ben Gharbia gives a compelling performance as Ismael.
