Kristy and Todd are two of Manny's friends at his high school and are madly in love with each other. When their romance is threatened by Todd's wealthy and snobbish parents, who employ Manny's mother as their maid, and Kristy's single working-class mother, Kristy and Todd make a suicide pact rather than end their romance. Mitch and Caroline rescue the teenage lovers. Meanwhile, Cody meets a mermaid while scuba diving who mistakes him for her long-lost love. But no one will believe Cody's story, except C.J, who together they attempt to track her down.

Caroline is sued by the mother of a victim of a failed rescue. C.J.'s desire for motherhood hits a snag when she realizes Cody's not ready for that type of commitment.
