The film opens with three men, Ron, Mark, and Peter, abandoning their boat in the middle of the ocean and happening upon an uncharted island.

After being captured by a gang of masked men, the three awaken to find themselves tied to crucifixes in the middle of a large militia camp.

The two remaining friends and a traitor named Leon are turned loose in the forest to be hunted down by Karl's army of trained killers.

Meanwhile, Karl's hired surgeon Dr. Senius is working on a breed of hideously deformed super soldiers that are going to replace the fallen ones in battle.

The surviving guard is punished for his disobedience by Karl when his spinal cord is torn from his anus with a large meat hook.

Then Karl deploys a heavily trained gang of assassins called the Black Demons to hunt down the remaining traitors and kill them.

After briefly confronting the ninjas and killing them, Son, Giang, and Leon plan a full-scale attack on the camp at sundown.

After reaching the main gates disguised as Black Demons with a prisoner, the two guards on patrol demand to know why Leon's still alive.

Senius stumbles back into his tent, where an unfinished super-soldier asphyxiates him in his open torso and subsequently tears off his head.

Violent Shit III was filmed outside of Hamburg, Germany in 1993, but due to financial concerns, it was not officially released until six years later.

Additionally, a techno instrumental called Blasphemic Beats plays over the closing credits accompanied by scenes from previous Violent Shit films.
