Nan moves into a new place with her new boyfriend. He introduces her to a guy (not sure if he's a friend of his or the caretaker of the place). She is shocked to find that the guy is her ex-boyfriend. Of course, they don't tell her new boyfriend about that. They rekindle their affair and make love whenever her boyfriend is not around. One time, while they are in the middle of lovemaking, her boyfriend suddenly comes home. Her ex-boyfriend has to hide under the bed and listen to her have sex with her new boyfriend.
