More giallo goodness from the master of the genre, Umberto Lenzi. This cinematic gem follows a wealthy widow who moves to a luxurious home in Italy, only to find herself the target of a mysterious but handsome stranger and his equally stunning step-sibling, so cue questionable debauchery, dangerous drugs and very saucy sex. Starring Hollywood hottie Carroll Baker this psychological thriller takes the genre into truly dark, surreal places whilst delivering a pitch perfect, claustrophobic atmosphere.
