A man must find a way to survive when he betrays a crime boss who paid him to take a dive in a fight. Circumstances lead him to the recruitment office of the Foreign Legion when he flees the men sent to kill him. He tries to take the girlfriend of the boss with him too but ultimately he must escape alone. Once enlisted in the Legion he is flown far away to the desert to fight a foreign conflict with primitive indigenous peoples. His “safety” is threatened when the henchmen from home arrive as new recruits to the outpost.
