September 1942 - With Erwin Rommel's Afrika Korps on the march through Egypt, a British special forces unit, composed of German Jews who serve with the British despite the mutual resentment between both, kidnap a Canadian officer who is an expert topographer and who is held prisoner by the Vichy French in Algeria. The officer, Donald Craig, must negotiate a company of British and German-Jewish commandos through 800 miles of the Sahara to aide a pending amphibious landing against Tobruk's massive fuel storage base - a mission that sees one impediment after another, and which discovers an undetected German armored force ready to win the battle of Egypt.

A young man is confined in a mental hospital. Through a flashback we see that he was traumatized as a child, when he and his family were circus performers: he saw his father cut off the arms of his mother, a religious fanatic and leader of the heretical church of Santa Sangre ("Holy Blood"), and then commit suicide. Back in the present, he escapes and rejoins his surviving and armless mother. Against his will, he "becomes her arms" and the two undertake a grisly campaign of murder and revenge.
