The chirpy, Euro-Barbara Windsor squeaking soundtrack that introduces this film would perhaps fool you into think you're about to watch some "Whoopsy-Boing!" sex comedy, but you'd be wrong. Except for the sex bit.
A horrible rich lady who has an open marriage with her Roman noble husband (Silvano Tranquili) is found dead within a locked room, her throat cut. Everyone thinks it was suicide...well, the police think it was suicide, but no one else does, especially housekeeper Magda, who now tends to the needs of Silvano and his mistress, photographer and professional moody looking smoker Rosalba Neri.
A spanner is thrown into the works when the rich lady's daughter from a previous marriage turns up after quitting boarding school (or something like that). Her wide eyed innocence certainly catches the eyes of Rosalba, who quickly bonds with the girl by taking loads of pictures of her and conveying the idea that she may bat for both sides, as it were. Silvano's eyebrows are certainly raised when comes home to find his step-daughter bare-arsed in front of a mirror, but if this newcomer has a legit stake in the money left by the rich jerk lady, what are out scheming twosome going to do about it?
This is more of your old-school giallo set in a big house with rich people being duplicitous and trying to out-do each other, with the usual plot twists thrown in for good measure, and a whole heap of photographer sessions between the young girl and a drooling Rosalba Neri. Obviously the girl gets it on with both the lead actors but you don't get a slow motion lesbian sex scene like you did with Silvio Amadio's previous Amuck. That said, those looking for nudity won't be let down as the stepdaughter seemingly spends half the film naked.
I've got to admit that I found the soundtrack really irritating. "A-chi-chi-chi-di-di-dididida-chi...aaaaaaaah!" indeed.
