Maurice plans a robbery on a rich house in the Paris suburb of Neuilly, along with Silien and another accomplice Remy (Philippe Nahon). However the robbery goes wrong as the police are informed in advance. Maurice escapes with his life, albeit injured, but passes out before waking up in his friend Jean's home miraculously rescued. It's clear that he was betrayed and all fingers seemingly point to Silien. Would such an apparently loyal friend really double-cross him? Or are there others in Maurice's life who aren't all they seem?
