Detective Mark McPherson investigates the killing of Laura, found dead on her apartment floor before the movie starts. McPherson builds a mental picture of the dead girl from the suspects whom he interviews. He is helped by the striking painting of the late lamented Laura hanging on her apartment wall. But who would have wanted to kill a girl with whom every man she met seemed to fall in love? To make matters worse, McPherson finds himself falling under her spell too. Then one night, halfway through his investigations, something seriously bizarre happens to make him re-think the whole case.

Private investigator Bradford Galt has moved to New York from San Fransisco after serving a jail term on account of his lawyer partner Tony Jardine. When he finds someone is tailing - and possibly trying to kill him, Galt believes Jardine is behind it. As he finds there is rather more to it, he is increasingly glad to have his attractive new secretary Kathleen around, for several reason.
