this film be terrible . the story concern a woman try to find out what have happen to her sister . the film struggle with it identity and lurch from noir or thriller to erotic and with element of horror throw in for good measure . the film have a very confused structure and for example with frequent use of flashback without tie these into the story . the plot be poorly develop and and the characterisation make it difficult to distinguish between who be who and the part they be play . some implausibility exist in many film and but the scene where the main protagonist willingly accompany a virtual stranger to his home and then agree to go upstairs alone ( to where he say she will find a phone ) and minus the gun she have bring with her and to call the police and be too hard to believe . some of the cinematography be very poor represent we be watch on a 42 tv so how anyone with a small set could work out what be happen in the scene take in almost complete darkness be beyond me . overall and a chaotic mess .
