Sea of Love

New York City homicide detective Frank Keller is a burned-out alcoholic. His wife left him and married one of his colleagues, and he is depressed about reaching his twentieth year on the police force. He is assigned to investigate the murder of a man in Manhattan who has been shot while face down in his bed, naked, and listening to an old 45 rpm record of the 1959 hit "Sea of Love". Keller has three clues: a lipstick-smeared cigarette, a want ad that the dead man placed in a newspaper, and fingerprints of the perpetrator.
