Michel takes up picking pockets as a hobby, and is arrested almost immediately, giving him the chance to reflect on the morality of crime. After his release, though, his mother dies, and he rejects the support of friends Jeanne and Jacques in favour of returning to pickpocketing (after taking lessons from an expert), because he realises that it's the only way he can express himself...

Michel passes the time by picking pockets, careful to never be caught despite being watched by the police. His friend Jacques may suspect, while both men may have their eyes on Jeanne, the pretty neighbor of Michel's ailing mother.
