Vice Versa

At the initiative of Nath, an environmental activist and Laurent's girlfriend, the group of friends Thomas, Laurent, Marc and Aude, will embark on a punitive expedition to a cosmetics laboratory. A series of incidents will cause an inexplicable phenomenon, a lightning bolt that strikes Thomas and causes a strange burn on his arm. And the next day, Thomas, stunned, wakes up transformed into a girl... Justin, his little brother, and Aude, his best friend, will be in on the secret and help Thomas hide this strange phenomenon.

Thomas, very disturbed by what happened to him, realizes that his transformation can be caused by a shock to his scar. He dreads going back to school more than anything, and will try to escape it by pretending to be sick, which is also contagious. Aude accompanies him to the doctor, but Thomas runs away and prefers to continue to hide everything, even if he gets a little tangled up in all his lies.

Finally back at high school, Thomas falls head over heels in love with Ally, a senior. His friends will overwhelm him with good advice on how to seduce her. So he will try his best to meet her, but he must also learn with Aude to master his new girly appearance, the all-important problems of clothes and makeup. And apparently, his "girl" version is more successful than his "boy" version. But with Ally, it's not a given this time.

Determined to make some pocket money, Thomas is forced to transform himself into a girl to get a babysitting job. He will discover that it is not so easy to look after a little pest named Lola, and to manage a baby's diapers. Fortunately, friends are there, and Aude, who had lost the diary where Thomas's whole story was told, will end up finding him where no one expected...

Faced with Thomas' disastrous school results, and the fact that they caught him dressed as a girl, his parents decide that he absolutely must see a shrink, who is also a shrink. She will not bear the revelation, and the parents will conclude that it is a classic teenage crisis.

Emmanuelle, having unwittingly saved Ally's grandmother's bag, will have to complete her civil status to face a notoriety that she would have gladly done without. Thomas will have a hard time destroying his image, and becoming happy and hidden again...

Aude only has eyes for Bastien, the football player. But Bastien only has eyes for Emmanuelle, who must learn how girls get rid of boys they don't want. And to top it all off, Nath is jealous of the female football players and forces Laurent to follow a draconian diet.

Thomas, more and more in love with Ally, will use Emmanuelle's appearance to join his girls' club, all fans of the series "Spy Witches". Aude tries in vain to oppose it. Thomas' attempts to attract Ally's good graces will end in a rather catastrophic way, but will have done Justin a good service.

Thomas, who accompanies Aude to a casting for singers, unwittingly transforms into Emmanuelle, and the two girls are selected for the final. But Aude falls ill, and Emmanuelle does not want to give up on running, which Aude experiences as a betrayal. The group must come to the aid of Nath, who is disturbed by the birth of her little brother.

Laurent has a brilliant idea: the group is going to do a reality TV show. Thomas falls heavily and breaks his arm. Surprise! The shock does not cause any transformation, and the process seems to have disappeared for good. After the joy of this realization, Thomas will miss Emmanuelle, especially since he could have won the young female writers' competition.

Thomas is furious to receive an English correspondent, who turns out to be a girl. Faced with the perfect understanding between Karen, his correspondent, and Aude, Thomas will take on the appearance of Emmanuelle to share the girls' little secrets. And he will discover that he is much more attractive than he thought.

Thomas is almost jealous of Emmanuelle's popularity. Noticing that his friends have just forgotten to wish him a happy birthday, he decides to participate in the weekend planned in Chamrousse in his female form, and to make her odious to everyone. But Emmanuelle, faced with Luc's suspicions about her true identity, will, once again, owe her salvation to Aude.

Marc, Thomas' best friend, is in love with Emmanuelle. Thomas is devastated. In addition, Thomas' parents and the high school principal are starting to think that this weird Emmanuelle is going too far. Life is becoming more and more difficult for Thomas. He will confess the truth to Marc, and make a desperate attempt to get rid of this decidedly too cumbersome female double once and for all. Fortunately, Marc, Aude and Justin are there...
