A minor earthquake prompts a geological survey team to come to Baywatch to plant a seismometer in an underwater fault line near Malibu Beach. When Stephanie falls for the team leader, her life, as wel as Hobie’s, Jackie’s and many others hang in the balance as the area is hit by a massive earthquake.
After a minor earthquake traumatizes CJ , a geological survey team arrives at Baywatch in order to place an underwater seismometer in the Malibu fault. The team requires a safety officer, and Stephanie volunteers, mainly because she has fallen for the team leader Riley Ferguson, an expert oceanographer and free-diver. She invites Riley to her apartment to discuss the details of the operation, but their budding romance is cut short when her sister, Caroline (Yasmine Bleeth), shows up without warning. Caroline has left her husband and has come to California to start a new life.
Hobie has a surprise of his own, when he tells Mitch he has decided to spend more time with his rock band rather than continue with Junior Lifeguards. When Mitch tries to reason with Hobie, he snaps back, telling Mitch that he doesn’t want to follow in his father’s footsteps. Meanwhile, Jackie Quinn has sold her cafe to a new owner and she and Summer are leaving California. After Summer flies home, Jackie will then drive their trailer back after spending one more night parked on a cliff overlooking the ocean. Back on the beach, Matt is having real problems with new lifeguard Logan Fowler, who is from Australia on a lifeguard exchange program. With his long hair and hot-dog ways, Logan infuriates Matt, who thinks Logan is concerned more with his own cocky heroism than with the safety of potential victims.
Early the next morning, Riley, Stephanie, and the geological team are at sea to plant the seismometer. However, when Riley is underwater installing the device, the area is hit by a massive earthquake, threatening everyone’s life. Riley is trapped underwater, CJ and Caroline’s apartment collapses, Jackie si caught in her trailer which is hanging precariously over the edge of a cliff, and Hobie is trapped under the rubble of a partially collapsed garage. The remaining Baywatch lifeguards must spring into action quickly to save them and other earthquake victims.
PART TWO
After a massive earthquake hits the Los Angeles area, the Baywatch lifeguards spring into action to save trapped victims, including Hobie, Jackie Quinn, Stephanie, and members of a geological survey team.
While Stephanie is off the coast of Malibu with a geological survey team that is planting an underwater seismometer in the Malibu fault, the entire area is suddenly hit by an enormous earthquake measuring 7.2 on the Richter Scale. Riley, the team leader, is trapped underwater, but his isn’t the only life in danger. Stephanie and the rest of the team are trapped at sea when their boat capsizes. Jackie Quinn is caught in a trailer that could plunge off a cliff at any moment, while Hobie is trapped under the rubble of a partially collapsed garage.
Mitch manages to rescue Hobie just before a heavy boat engine falls on him, but Hobie is traumatized and determined to leave California. Rescuing Jackie and Riley proves to be more dangerous. Jackie’s trailer is precariously balanced on the edge of a cliff, and there is no way to reach it by land, since a landslide has blocked the highway leading there. Mitch and Matt plan on scaling the cliff to Jackie’s trailer in order to reach her. However, the sudden arrival of a news helicopter saves them valuable time by airlifting them to the top, and with the help of a heroic pilot, Mitch and Matt rescue Jackie just before the car attached to the trailer plunges to the rocks below in a huge fireball.
Meanwhile, Stephanie risks her life by free-diving to Riley, who is trapped under the surface. She tries to release him from the rocks which have trapped him, and almost drowns in the process. CJ and Logan arrive with a rescue team, and CJ manages to save Stephanie and free Riley just before he runs out of air. On the surface, Logan cuts a deal with one of the geologists, offering to also retrieve their computer…for a price. However, this could get Logan sent back to Australia for good.
