Civil War veteran-turned-rancher John Benedict (William Holden) returns home from a hunting trip to discover that a ruthless renegade and his murderous gang of rogues have killed his wife and children. But when Benedict recruits six condemned men to help him extract fatal revenge, he realizes that his newly formed posse answers to no one - they are wild, dangerous and unpredictable killers, much like the men they are pursuing. Will they carry out Benedict's plan or turn the tables and add him to their list of victims?
