A housekeeper lives in an old tower together with her grandson and the landlord’s daughter (Anna Maria Pierangeli). Whenever these three receive a guest, they kill him.
In the 16th minute Anna Maria Pierangeli (AKA Pier Angeli) leans over a man to cut him with a knife. From her cleavage her nipples pop out. Half an hour later a malicious person removes the actress’ shirt, revealing her firm, round breasts.
