Ilsa, the Wicked Warden (originally released as Greta: Haus Ohne Männer, and also known as Greta, the Mad Butcher, Ilsa: Absolute Power, and Wanda, the Wicked Warden) is a 1977 sexploitation film directed by Jesús Franco and starring Dyanne Thorne. The film is considered to be the third entry in the Ilsa film series, but was not originally filmed with the intent of being as such, despite starring Dyanne Thorne. The film's plot follows Ilsa, a warden at a psychiatric hospital for young women, and a girl who feigns illness so that she can investigate what happened to her sister who stayed at the hospital.
