Mike and Helena are living an almost perfect life until Lacy, Helena's sister, comes to spend a few days with them. After dinner, while his wife goes upstairs to sleep after drinking a little too much, Mike decides to stay a little longer to "chat" with the pretty redhead. The next morning, as the couple fell asleep in the living room after a long night of pleasure, Helena almost surprises them. Mike then has to find a good excuse to justify not having gone to bed with his wife.
