Doug Glatt is a polite, kind-hearted, but
dim-witted bouncer at a local dive bar in the fictional hockey crazed town of Orangetown,
Massachusetts. He feels ostracized from society, especially since his father and brother are both highly educated wealthy and successful
physicians. Doug attends a local
minor league hockey game with his best friend, Pat, who hosts a public broadcast show recapping weekly hockey highlights called Hot Ice. Pat taunts the visiting team during a
fight and one of their players climbs into the stands while shouting out a homophobic slur. Doug, whose brother is
gay, steps in and easily beats up the opposing player. The next day, he gets a phone call from the coach of his hometown team Orangetown Assassins, who offers him a tryout to be an
enforcer. He gets the position despite being a weak skater, and trains relentlessly to bring his skills up to par. Meanwhile, legendary veteran enforcer, Ross "The Boss" Rhea is demoted to the minors after serving a 20-game suspension for slashing an opponent in the head from behind. Three years prior, he hit and
concussed the highly skilled prospect Xavier Laflamme, who has had trouble recovering from the incident due to his fear of being hit again. As a result, Laflamme is still stuck in the minors, playing for the
Halifax Highlanders. As Doug's reputation grows, he earns the nickname "Doug the Thug". The head coach of the Assassins tells Doug that his brother, Highlanders' coach Ronnie, wants to hire him to protect Laflamme and be his roommate. The Highlanders experience success with Doug as their enforcer, and he quickly becomes popular among fans and teammates, much to the disapproval of his parents and Laflamme, who loses ice time and the
alternate-captaincy to him. Doug meets Eva,
a hockey fan with a penchant for sleeping with players at a bar in Halifax and the two become romantically involved. With four games left on their schedule, the Highlanders need two wins to secure a playoff spot. On a road game in
Quebec, after an opposing player concusses Laflamme with a heavy hit, Doug savagely beats the player unconscious and is suspended for the next game against Rhea and the
St. John's Shamrocks. Doug encounters Rhea at a
diner, where Rhea dismisses his belief that he is a hockey player, insisting that they are both "goons", and asserts that fans just want to see them bleed. Though Rhea acknowledges Doug's physical prowess and gives Doug his respect, he warns him that if they ever meet on the ice, he will not hold back. The Highlanders, with Doug suspended and Laflamme hospitalized, lose to the Shamrocks. The aging captain of the Highlanders, an inexperienced fighter, challenges Ross to a fight. Ross offers him a chance to back out but the player declines and quickly loses. Doug reaches out to Laflamme and promises to always protect him on the ice; the incident touches Laflamme, who reconsiders his animosity towards him. In their next game, the Highlanders lead 2-1 thanks to strong teamwork between Doug and Laflamme. In the final seconds, Doug blocks a slapshot with his face and his ankle is injured in the ensuing scramble. The Highlanders win, but still need a win in a rematch with Rhea and the Shamrocks in their last game for a playoff spot. Eva breaks up with her boyfriend to be with Doug, declaring that she loves him. Doug later allows her now-ex-boyfriend to beat him up, believing that he deserves it for coming between them. After two periods, the Shamrocks are beating the Highlanders 2–0. Rhea and Doug mutually agree to fight in the third period. Although Rhea manages to knock him down and Doug re-breaks his recently injured ankle, Doug refuses to back down and eventually emerges victorious, leaving Rhea incapacitated on the ice, and knocking his tooth out. Ross smiles at seeing his tooth, satisfied that he lost to someone he considers a worthy opponent. Eva and his teammates help a seriously injured Doug off the ice and Laflamme, inspired by Rhea's defeat, scores a
natural hat trick, giving the Highlanders a 3–2 lead. As the game enters its final minute, Eva comforts Doug in the locker room as he comments, "I think I nailed him." ==Cast==
