Janell and Charlies are visiting a mountain town on a skiing trip and invite a local babysittter Lessie to watch their child while they ski. The couple come back early drunk and silly. Lessie is somewhat awkward and the child she was watching has been asleep for hours. Immediately the older couple strip naked and invite the babysitter to join them. Despite the innocent young lady's immediate reservations, Lessie is excited by the copious attention doled out to her by both of the attractive couple.
