Edouard Coleman (Alain Delon) spends his days and nights chasing criminals, but doesn't see the crook right under his nose. Simon (Richard Crenna), a smooth nightclub owner, works with a small crew to execute daring heists with big payoffs, while the beautiful Cathy (Catherine Deneuve) is torn between them. As cop and criminal do what they do best, paths converge and old scores must be settled.
