this be probably one of brian de palma best know movie but it isn not his best . body double and the fury and carrie be good movie but this movie be good than blow out and obsession . de palma be very influenced by hitchcock and this movie be a take off on psycho . angie dickinson be a bored housewife who be think of have an affair and after her psychiatrist and play by michael caine and turn down an offer and dickinson meet a man in a art gallery and she wind up sleep with him . after this point it best you do not know what happen but there be a murder and nancy allen be a call girl who get a look at the killer . dennis franz be the detective on the case who really doesn not trust allen and she have to find the killer herself . it a pretty good movie but isn not one of de palma best .
