Bloodsport: The Dark Kumite

Action hero and martial artist Daniel Bernhardt is back in Bloodsport 4 (playing a different character to his character in 2 and 3 but under the same franchise name) and is a cop who has to go undercover in a brutal prison with people he locked away to find out why people are dying and disappearing (he has help on the inside), and Blare (Lisa Stothard) is his partner on the outside (Bernhardt and Stothard got together in real life after meeting on the set and have a daughter) feeding him information and collecting it in disguise as a nun. He will have to fight for the wardens' pleasure in order to find out what's going on though. Can he survive the madness with his coworkers, expose the atrocities and avoid total annihilation?
