For the holidays, Paul's father has the two of them staying with his girlfriend, Monica, and her two daughters. Paul doesn't mind, though, because all three ladies tend to wear pantyhose. But he takes things a little too far by stealing pantyhose from each of them for his own use. When he returns from Christmas shopping and finds that the stash has been placed on his bed as a sign that he's been found out, he starts to panic. Which one of them discovered his shameful secret? Chelsea, the older and hard-to-read one? Allison, the younger and more playful one? Or was it his father's girlfriend? The mystery keeps him guessing all throughout Christmas Eve, and when he finds out the answer, it leads to a Christmas gift that he won't soon forget.
