Beautiful Natasha was to inherit a fortune on her 21st birthday. Her step-parents want her cash so she is transported, hooded and in bondage to a converted, private insane asylum hidden away deep in the Derbyshire Pennines. It's owner, the glamorous Miss Blackstone, her dapper partner, Bradwell, the sadistic nurses, the mute orderly and other perverted staff keep a number of female inmates confined as fetishistic playthings for the sake of wealthy clients wishing to remove the girls from the public eye. Sexually exploited and subjected to devious punishments amidst varied fiendishly contrived devices, Natasha is determined to escape and reveal their schemes to the outside world.
Thwarted and subjected to stricter restraints and sexual supervision, she learns she will have to participate before an ogling audience of Miss Blackstone's clients in the forthcoming, elaborate fetish party night. There, blatant acts of lust and sexual humiliation will be the evening's entertainment. Teamed up with nymphomaniac secretary, Miss Crosby, herself now a victim, Natasha must find a way out. But how?
