Defiantly refusing to make narrative sense, this revolves around two evil houses - one in Rome, one in New York - and the witch-like goddesses who haunt them. A succession of unfortunate mortals become intrigued by the mysteries surrounding the houses, and mainly come to bad ends in sequences staged by Argento with all the imaginative flair of Busby Berkeley dance routines.
Argento goes overboard with the vivid camera work, and anyone expecting a story is doomed to extreme frustration. There is, surprisingly, an unusual degree of cynical humour to the proceedings and the requisite collection of blankly beautiful actresses. The kind of film that starts off with a climax and builds to a plateau of surrealist delirium that, one way or another, will have you shrieking.
