Simon is 14 years old, and like most teenagers, he has a hard time going through this ungrateful period. He’s generally awkward and has lived for a long time in the shadow of his friend Stéphane, who’s better looking and more popular than he is. One morning, Stéphane asks Simon if he can borrow his bedroom to have sex with Sophie, a girl with whom Simon is secretely in love. This request will shatter the two boys’ friendship, and for the first time, Simon will stand up to Stéphane. A move which will mark his first step into adulthood.
