The anti-government guerrillas are fighting against the government's military forces in the country that is at political unrest. Suddenly, there is an incident in which a woman was raped and murdered in a small village. Guerrillas are the suspected culprit of that incident.

Mr. Prosper, the Lieutenant of the military, was sent together with his men to this small village to investigate the incident and hunt down the guerrillas. But the incident was actually all planned out by him so that he could have a gang rape party for himself. All women who were suspected of being guerrillas were arrested. That was the beginning of the insane gang rape party.
