This film finds Ilsa, vicious she-wolf of the SS, running a mental-hospital for young women. This doesn't bode well for anybody involved. A girl deliberately "checks" in to the hospital to find out what has happened to her sister who stayed there. Meanwhile Ilsa and one of the guards are forcing the inmates to have sex with male prisoners, filming them and selling them as pornoflicks. Directed by the visionary Jesus Franco, this installment of Ilsa's saga is the sickest of them all.
