Le Pacha

In Paris, there is the heist of priceless gems from an armored car and the police escort in an empty road. The criminal Quinquin delivers the packages of gems to the dealer Marcel le Coreen and receives the payment for the robbery. Instead of sharing the money with his gang, Quiquin kills them all. Meanwhile, Inspector Joss is investigating the heist and learns that his childhood friend, Inspector Gouvion, was the only survivor from the attack. When Gouvion is found dead by a gunshot in his apartment, there is a doubt whether it was an accident or suicide. However, Joss believes he was murdered. When the body of the gangster Leon is found shot in a submerged car in a lake, Joss meets his sister Nathalie Villar, who works in a nightclub and knows Gouvion, and begins to resolve the cases.
