It is 1943 and secretly the Nazis believe the war can't be won, thus twelve young Nazi hot shots are going to be sent to the Middle East to lay the foundations for the Fourth Reich. Major Wright (Telly Savalas) recruits another bunch of condemned and hopeless convicts for another suicide mission to go deep into Nazi held eastern Europe and kill the Nazis before they can reach Istanbul.
To make things more complicated, one of the Major's Dirty Dozen is a Nazi spy and is intent on sabotaging the mission. The Major thus changes his plan on the fly though this could mean his men become targets of the RAF!
A rather by-the-numbers TV movie, it has the usual tired tropes of crack SS stormtroopers not being able to shoot straight plus the premise doesn't really make a lot of sense. It is fine enough to watch if you just want some wartime action and not worry too much about quite why!
