Robin Williams stars in this thriller written and directed by Mark Romanek. Sy Parrish (Williams) is a middle-aged loner who works as a photograph developer in a supermarket.

He has gradually become obsessed with one family, the Yorkins, who regularly come to his counter, making duplicates of each film they bring in to be developed and pinning the photographs to the walls of his apartment.

When Sy realises that Will Yorkin (Michael Vartan) is cheating on wife Nina (Connie Nielsen), he steps up his silent interaction with the family, placing evidence of the infidelity in an envelope of photos he has recently developed for young Jake Yorkin (Dylan Smith). Soon however, Parrish reveals his hand, and the Yorkin family realise the full horror of their situation.
