The night after getting out of prison, Lucas Blackstone (Angus Macfadyen) breaks into a rural home and steals a pistol and bottle of whiskey. Later that evening, he sneaks around in the darkness near the campsite of Shawn Everett (Bradley Dorsey) and his wife, Carrie (Haylie Duff), a young couple coping with a strained marriage. Lucas kidnaps Shawn and Carrie at gunpoint, forcing Shawn to drive him to an address in town of Trinity. Lucas pries and discovers that Shawn had an affair. Amused by the couple's seemingly vain attempt to reconcile their marriage, Lucas mocks Carrie's claim that she has forgiven Shawn, saying it is impossible to forgive something like that. Soon after, Shawn and Carrie learn that a man nicknamed Trig from Trinity murdered Lucas' 10-year-old son, Max. Also unable to forgive, Lucas is bent on justice. When they arrive in Trinity, Lucas will kill Trig.
