Fed up with being preyed upon at school by loudmouth bully George, friends Sam, Clyde and Millie decide to teach their tormentor a lesson. Inviting him out on a boat trip to celebrate Sam's birthday and joined by Sam's older brother and his friend, the group plans a prank that will put George in his place. By the end of the day, however, this close-knit group of friends will have been tested and torn apart by a series of tricky moral decisions. Mean Creek masterfully captures the lives of a group of teenagers and the effect on them when a moment of misjudgment spirals out of control.
