　　A young couple retreat to a glass house for two weeks of celibate self-improvement but are disturbed by a lost hiker. As the stranger reveals more of himself, their feelings move from pity to revulsion and they must make a decision about what to do with him. But when the crisis is seemingly settled, strange forces compel all three to replay this scenario again.
