At Folsom State Prison, several inmates escape...including killer Arnold Kluger, who swore revenge on the detective and district attorney responsible for his conviction. Despite precautions, the two men are soon in Kluger's power, together with showgirl Carol whom he suspects of informing on him. At a shack in the California desert, Kluger, two henchmen, and four hostages wait, and wait, for an escape plane that may never come.
