Nanny and amateur photographer, Kristin, is plagued by a horrifying recurring nightmare. In the nightmare she arrives at the aftermath of a shootout where she spies four bodies and a detective, and she can't help but photograph the ghastly scene. The following morning Kristin is greeted with this very same scene as she walks to work - she is terrified by the realisation of her dream. Kristin's life is complicated: her lover Michael is married, and the father of the children she looks after. His wife is a nasty, icy woman. But things are set to get worse. She starts seeing people on the streets of New York who she knows are dead: her grandfather, a local from her home town. And when she studies her photographs of these people, their bodies appear to be transparent, just like the bodies in the photographs of her nightmare. Kristin feels like she's going mad, nothing seems to make any sense...
