An obnoxious group of friends struggle to survive the stag weekend from hell as a deer-hunting expedition quickly turns messy. Timid teacher Ian Telford joins the stag weekend of his brother-in-law Johnners and several of his obnoxious friends, as they embark on a deer-stalking adventure in the remote Scottish Highlands, organised by best man Ledge. But it's not long before the hunters become the prey, and their friendship is tested to the limit in a ruthless battle for survival.
