Eight men set off on a hunting trip in the Scottish Highlands, a stag party for "Johnners". Ian, the bride's brother, is a last minute addition to the party after somebody else dropped out. Being less of an alpha male than the others, he is immediately singled out for ridicule, but remains with the group because he has promised his sister that he will look after her fiancé. After insulting the gamekeeper who best man "Ledge" has hired to take them hunting in the woods, the group is abandoned by the old man, leaving them to fend for themselves. After they set up camp, a mysterious figure begins killing them off one by one. The group soon find themselves running for their lives, all while speculating who the killer could be.
