Philippe Jordan is a policeman prone to advancing the cause of justice by any means necessary. On his agenda is a powerful drug cartel working out of Paris and Marseilles, with a drug lord who is essentially inaccessible -- but not immortal.

After serving together in the French Foreign Legion, a mercenary and a doctor leave the service and go their separate ways. Later, they are reunited and become involved with a caper involving millions in a high-security safe. The two men become locked in during a holiday weekend as they attempt to crack the safe's combination.
