Incest to beat all incest. Brother and sister have been getting it on between each other for years because they could not find anyone who could satisfy them better than the love they had for each other. The sister had been divorced because her husband wanted a younger girl, so the brother moves in with his sister who had three kids, since he was helping pay some of the bills anyway.
Mom did not want to get re-married anytime soon. What she really wanted was to make her fantasy about making it with her son, his friends and others become a reality.
A single mum, worried by her fifteen-year-old son's increasingly hermit-like lifestyle, decides to re-create a camping trip she'd taken years earlier with her father. It doesn't go entirely to plan.
