Based on Richard Stark's novel "The Score", this is the story of a commando-like attack on a small mining town. The "finger" giving the plan to the crew also ends up being its nemesis.

Edgar, the former accountant of the Martens factory, organizes a daring heist in Servage, a small town in the French Alps. His plan envisages neutralizing the police station, the fire station and the telephone switchboard during the night. When this is done, his men will be able to quietly hold up the bank, the post office safe, the payroll of the local factory and two or three department stores. To lead the commando, Edgar hires Georges, a professional gangster, eager to do a perfect job. The plan is brilliant but not everything will go according to it.—Guy Bellinger
