Abbie Phillips (Tania Busselier) suspects her sister – lets call her Sophie, shall we? – is being mistreated in a mental hospital. When she looses all contact with Sophie, she comes up with a plan to have herself committed to the asylum by Dr. Arcos (Jess Franco), who on his terms also suspects foul play within the walls of the institute. That’s her way to try and find out what happened to her sister. With holding the friendly Dr. Arcos at gunpoint while explaining her idea, you can already suspect that she didn’t think things through properly, let alone this being one of the more clever ideas she ever came up with. A poor girl with a plan doomed to failure, as the place she so desperately wants to get into is run be Greta (that’s re-incarnated as the exact spitting image of Dyanne Thorne), a very nasty warden who’s only joy in life seems to be torturing women, throwing depraved sex & rape parties, playing vicious S&M games and a bit of that good old killing for pleasure too.
