Homer and Marge are having a romantic swim in the ocean outside an island resort called The Yellow Lotus when they encounter a dead body.
One week earlier, the Simpsons arrive at the resort after earning enough points to use a timeshare, which Homer was duped into buying from Nick Callahan ten years ago.
While fleeing, they pass Dr. Hibbert, who is confronting Bernice about her drugs, and encounter Nick Callahan trying to defraud a couple.
Security catches the Simpsons, but Marge and Homer decide to swim in the ocean as they wait for a ferry to take them home.
Above in a hot air balloon, Dr. Hibbert throws Bernice's drugs into the ocean where they are consumed by a sea otter.
Meanwhile, the drug-addled sea otter attacks and kills a snorkeling Callahan, whose body drifts toward Homer and Marge.
