The Little Thief (2000)

In this French drama, a teenager falls into a life of crime, little realizing the consequences. S. is a moody young man who loses his job at a bakery, and decides to throw in his lot with a group of thieves about the same age as himself. S. and his cronies are strictly small-timers, pulling off second-rate break-ins for an older crime boss, but his willingness to do what he's told helps him rise up the ladder to bigger and more lucrative jobs. However, S. lacks the maturity or experience to deal with the risks, and after a few disastrous mistakes, he finds his fortunes sinking far faster than they rose.
