Surf's Up

S6, E4: After a number of unusual circumstances occur around the beaches, including Cody and Neely rescuing two surfer boys that come down with a fever, an environmentalist group comes to Baywatch to protest the dumping of chemicals from the storm drains, and Mitch enlists the Beach Boys for a benefit concert to help out raise money for repairing the storm drains. Meanwhile, Stephanie's ex-husband, Billy, suddenly turns up much to her uncertainty and Caroline's wariness. Also, Neely begins wooing Cody while teaching him the ropes of surfing while she also confides in him about how she prides herself being the 'bad girl' and persuades him to embrace his own dark side.
