Peter and Ann are kidnapped by a modern-day gladiatorial entrepreneur. The newly married members of a kick-boxing school had been spotted by Jake Tompkins, investigated, and then transported to his island. There they are modified and trained in the most brutal and sadistic form of unarmed fighting ever devised. Once trained, they are put on show to compete, not only at kick-boxing but other forms of combat as well. He also offers them as sexual slaves to his clients who are willing to pay enormous sums to do whatever they wish.
