Mona et Moi plot
A part of an abandoned factory in Ivry near Paris has been converted into a sports center where young people can practice boxing or martial arts. Olivier's father owns the buildings. His son lives with two friends, Pierre and Ricky. Pierre says he is an artist because he likes books. Ricky poses as a trader. He breeds a python named Gaëtan and amuses himself like a child with a revolver. Olivier plucks a bit on a guitar but still has the presence of a rocker. All three share the same passion: they like rock music, have little talent and sniff coke. Pierre likes Mona, a cashier in a supermarket.
