Alain Delon plays Jef Costello, a hitman who is hired to murder a nightclub owner. His perfect planning and airtight alibi enable him to elude the police, until his obsession with the nightclub's beautiful pianist (a witness to the crime) clouds his judgement.
A beautifully atmospheric movie with a visual style unseen since the noir films of the 40's. The cast are wonderfully subtle as is the understated directing and dramatic cinematography. A contemporary classic.
