Three girls gets lost while enjoying skiing. The weather gets stormy and they can't find a way to go back. When they are at a loss what to do, a man appears and takes them to his house. They drink coffee and feel relaxed... The man suddenly stands up and says, "Who goes first?" They don't know what he's trying say, until he declares: "I saved you. You must repay me! If you don't, just get out of here!" Like this, the man sexually assaults the girls one by one...
