After a peaceful sailboat ride, four young people, including rich kid Bill, Joe, Fred and Jane, knock on the door of a secluded villa after their dune buggy runs out of gas. Earlier in the day, Bill had given the lovely Jane a pearl necklace with a supposedly paranormal history, and this later opens up a can of worms. They are invited to spend the night at the mansion, owned by Lord Alexander and Lady Alexander, who happen to be hosting a strange ceremony that night attended by a group of eccentrics in black robes. During the evening, Jane exits her sleep chamber, seemingly in some kind of trance, and is lured to a sacrificial alter where the robed houseguests are hovering over her. As a knife is about to be plunged into the young lady, her three friends come to the rescue, but they are also witness to a chaotic mass murder catastrophe in which they flee with feelings of guilt and uncertainty.

An action drama about an assassin who is ordered to kill an old friend and the repercussions when he refuses. At the same time, although it has nothing to do with the plot, there seems to be a relentless undercurrent of sadism and masochism with a homosexual aura.

Tony Pintana, an art collector, and his wife are contacted by Martin, who is short on cash and proposes to rob a museum of a Indian golden mask that's worth 10 million dollar. When their attempt miserably fails, the museum decides to have the mask transported to a safer location. The three try their luck again and are successful this time. Chased by a policeman who isn't convinced they're innocent, the three will have a difficult time selling the mask on the black market.
