Doug Glatt (Seann William Scott), is a polite, kind-hearted, but dimwitted bouncer at a bar in Massachusetts. Doug feels ostracized from society, especially since his father and brother are both successful physicians. Doug attends a minor league hockey game with his best friend Pat (Jay Baruchel). Pat taunts the visiting team during a fighting in ice hockey and one of their players climbs into the stands, calling him a homophobic slur. Doug, whose brother is gay, steps in and easily beats up the opposing player. Soon after, Doug gets a phone call from the coach of his hometown team, who offers him a job as an enforcer (ice hockey).
Injury and family push hockey player Doug Glatt into retirement, but his plans change when his beloved former team appoints his nemesis as captain.
