The Caller

A mysterious man, "The Caller" (Malcolm McDowell), joins a woman, "The Girl" (Madolyn Smith), in a forest cabin, claiming his car has broken down and he needs to use her telephone. As they examine each other's stories for inconsistencies, the situation quickly becomes suspicious. The climax reveals that the woods are actually a weekly experiment where "points" are awarded to The Girl for finding flaws in The Caller's story, with a reward of 50 points for escaping.
