Isolated by loneliness, photo developer Sy Parrish (Williams) spirals headlong into an obsession with the private lives of long-time customers, the
Yorkins. Through years of developing the Yorkins' snapshots, Sy deludes himself into believing that he is a member of the family that barely knows
he exists. The fine line between Sy's fantasies and reality begins to blur as he injects his presence into the family's lives.
When the Yorkins face a crisis that threatens to tear them apart, Sy catapults into action, driven by a need to preserve his picture-perfect family.
But his link to the Yorkin family photos is cut off when he is fired by Bill Owens (Cole), an act that begins Sy's meltdown.
