Detective Mark McPherson explores the murder of Laura, located dead on her apartment or condo floor before the film starts. McPherson builds a mental image of the dead woman from the suspects whom he interviews. He is assisted by the striking paint of the late lamented Laura hanging on her home wall surface. But that would certainly have intended to eliminate a girl with which every guy she met seemed to fall in love? To make issues worse, McPherson finds himself dropping under her spell too. After that one night, midway via his investigations, something seriously unusual occurs making him re-think the entire case.
