Surf's Up

Die Diabolo-Bucht, für Surfer ein Paradies, ist so stark verschmutzt, dass die Rettungsschwimmer sie sperren. Zwei Jungen schlagen jedoch die Warnungen in den Wind. Kaum im Wasser, wird es einem der Jungen so schlecht, dass er zu ertrinken droht. Neely muss ihn retten.

Diablo Cove is one of the most popular surfing areas in Los Angeles. But unfortunately because of a storm drain, the water has been polluted and by that endangered the health of those surfing there. Cody and Neely take water samples there and discover dangerous levels of E Coli bacteria. But two teenagers named Stick and Daryl surf there anyway. When one of them gets sick and must be rescued by Cody and Neely, they discover that his back is completely covered with nasty rashes. After that, the lifeguards close the beach. After the close down, Mitch contacts Dave at the Surfrider Foundation. The Surfrider Foundation is a non-profit organization created to clean up shoreline pollution. Dave has wanted the storm drain diverted for years, but the county always refuse. At the beach where the Surfrider Foundation is having a meeting, Stephanie meets her ex-husband Billy again. He has retired from his job in New York and moved back to L.A. He did so when he suffered from a minor heart attack.

Después de que ocurran una serie de circunstancias inusuales alrededor de las playas, incluido Cody y Neely que rescatan a dos surfistas que tienen fiebre, un grupo ambientalista llega a Baywatch para protestar por el vertido de productos químicos en los desagües pluviales, y Mitch recluta a los Beach Boys para un concierto benéfico para ayudar a recaudar fondos para reparar los desagües pluviales.
