John Howland travels to the frozen North to build a branch of the Hudson Bay Railroad. There he meets and falls in love with Meleese Thoreau who warns him that her three bloodthirsty brothers, Max, Pierre and François, have sworn vengeance against a man named John Howland, the son of a man who killed their mother, and that torture and death await him along the route to his station.
