It's been six months since his six-year-old daughter was purportedly abducted in the Port Authority Bus Terminal in New York from under his watch, and William Keane (Damian Lewis) is barely able to cope. Repeatedly drawn to the site of the abduction, Keane wanders the bus station compulsively going over the events of that fateful day. Veering between days of relentless searching and nights of alcohol and drug induced extremes of self-destructive behavior, he struggles to maintain his sanity. Then one day he meets a financially strapped young woman, Lynn Bedik (Amy Ryan), and her 7-year-old daughter, Kira (Abigail Breslin), who are also staying at the same transient motel in New Jersey. As he becomes increasingly attached to the child, Keane starts to deal with his own feelings of loss and redemption and attempts to fill the void left by his daughter’s disappearance.
