Film Synopsis

Nancy, an attractive young American, is hitch-hiking her way down the Italian coastline when she is attacked by a stranger.  Narrowly avoiding being raped, she takes refuge in a grand villa belonging to the ageing English millionaire Joseph Noblart, who is presently hosting one of his lavish parties.  His guests make a colourful crowd, which includes Alex, Noblart's eccentric nephew, a man obsessed with sexual perversions of all kinds.  Nancy is welcomed as a guest and invited to stay.  Graciously she accepts, not knowing that Alex will take advantage of her presence to spy on her through a peep hole in her bedroom wall.  The day after her arrival in this shrine to hedonistic excess, the American begins to fall prey to a succession of bizarre fantasies...
