In spring 1961 a French commando is send out to destroy a medical supply camp of the Algerian Liberation Movement. With the exception of commander Perrin all of the soldiers had been conscripted from Britanny and are all opposed to the war. At first its only the harsh conditions of the desert that the men have to deal with. But soon enough they have to fight and kill in order not get killed themselves. The longer they are exposed to the terror snd cruelity of the fighting, the more these formerly peace-loving men turn into unscrupulous killing machines. When an Algerian FLN prisoner is bound to a radio mast in the torrid heat the day before his execution, one of the soldiers, Noel, decides to end this humiliation and to leave Perrin`s inhumane command behind. He frees the captive and the two escape.
