Bare knuckles and bare boobs!

Very familiar plot - man has to go into jail to uncover cagefight ring being run inside the jail by the crooked warden. The guests are the usual ultra rich men and women who want to see real blood.
This movie tends to accent sex somewhat more than most of the films of this type. So in between bloody cage fights we see a lot of half naked women - usually with silicone enhanced breasts - floating about. One such lady is offered to our hero for performing well in the ring but - being a married man with a high sense of ethics - he (somewhat reluctantly it has to be said) turns the said lady down.
Meanwhile he has to prepare himself to face the cagefights worst killer - a huge black dude built like a Sherman tank and going by the name of The President(!)
All in all its predictable but - thanks to the gratuitous sleaze element - pretty enjoyable for all that.
