It's the office worker's ultimate nightmare: being stuck in a lift that's going nowhere, unless it's down and fast, too fast, with oblivion waiting at the bottom. Not only that, but your last moments are to be spent listening to the creak of fraying wires. The four unlucky elevator riders in this tense shocker are an accountant, a punky youth, an attractive young woman and a mysterious third man. Long-term frustrations clash with instant rivalries: in extremis the truth will out. One by one, the cables snap. Think Huis Clos without the existentialism. Director Schenkel went on to make, among other things, Tarzan and the Lost City: what is it with him and swinging from ropes? Not one for claustrophobes.
