Cause I'm always ready, I won't let you out of my sight
Une brigade de sauvetage du comté de Los Angeles (L.A. County Beach Patrol) menée par le lieutenant Mitch Buchannon et composée d'une dizaine de sauveteurs doit faire face chaque jour aux dangers de la plage de Malibu, tout en composant avec leur vie personnelle.
Mitch Buchannon didn't die in a boat explosion in the 10th season but has been recovering from amnesia in Los Angeles. Mitch returns to Hawaii to get married again! His new fiancée Allison looks a lot like Lt. Stephanie Holden, a past love. Little does he know, Allison is cooperating with Mason Sato who appeared in the show's 2nd season and now returns for revenge. The Baywatchers are invited to Hawaii by CJ. She's opening CJ's Bar & Grill at the Turtle Bay Resort. Coincidentally, Caroline Holden is already there filming a soap opera. Neely Capshaw (ex-Mrs. Buchannon) comes to Hawaii to stop the wedding. She wants Mitch back!
