Mutant Maniacs (1996)

The son of a businessman and his bodyguard are kidnapped by a group of terrorists. With the ransom money they hope to buy more weapons and thus finance the revolution. One of the terrorists, a torturing doctor, decides to use his bodyguard to perform his sexual activities and shoot a snuff-movie. The problems for the group begin when the businessman refuses to pay for his son's life, claiming that he is a bloody drug addict and is worthless. Eliminating the hostage may not be such a simple solution, especially when he refuses to die.
