Coincidence and the aftermath of violence. A man's middle-school daughter has been murdered. His wife is already deceased. He tells a counselor he wants to live in anonymity, working with his hands. He moves away and gets a job in a factory. The woman who is the mother of the killer wants to apologize to the father, although she knows it would change nothing. He refuses to meet. She moves back to her hometown. She works in the kitchen at an inn where the man now lives. No one speaks. He eats alone. He reads in his apartment. She walks to her home and has a sandwich. She keeps her eyes lowered. He drives to work. Does either want to connect? What bond can they establish?
