Sex columnist Josie Hart makes her readers fantasies come true, but she's about to live one of her own.
At 55:12, two married couples, Tom and his wife Jane, and Tom's best friend Dick and his wife Karen, go on vacation together. Through dialog, we first learn that Tom and Karen are having an affair, and later also learn that Dick and Jane are also having an affair. When Dick and Jane go to the woods to camp by themselves, Tom and Karen become suspicious so they follow them to their camping spot and find them having sex. They return to the cottage, with Karen fuming madly. Tom pacifies her and tells her that it's the two of them who belong together, and they also have sex.
