Blue Ruin

Dwight Evans, living as a beach vagrant, lives out of his car and scavenges for food and money. A policewoman tells him that Wade Cleland, the man who murdered Dwight's parents twenty years ago, is to be released from prison, having received a lower sentence due to a plea bargain. Dwight returns to his hometown in Virginia and watches the Clelands collect Wade from prison. Despite failing to steal a gun, Dwight follows Wade to a club restroom and, after a fight, fatally stabs him. Realizing he dropped his car keys in the club, Dwight steals the Clelands' limousine; as he drives away, he discovers a teenage boy, William Cleland, in the back and lets him go.
