Crazy Desires of a Murderer (1977)

A young Countess, Ileana, arrives to her family mansion with her friends, most of which are hippies and students belonging to subversive movements. The mansion is inhabited by Ileana's father who's tetraplegic and unable to communicate following a severe paralysis, and her younger brother, who's mentally alienated and devoted to embalming animals. Berta, the housekeeper, and the family doctor, also reside in the house. Some of Ileana's guests start to get inexplicably killed. The killer also removes the victims' eyeballs.

Crazy Desires of a Murderer is a horror movie featuring Isabelle Marchall and directed by Filippo Walter Ratti.
