 Megan, the Australian lifeguard and marine biologist, is attacked by a crazed fisherman who also attacks another woman. While Megan deals with the trauma of escaping from her attacker, the psycho targets Megan and becomes determined to track her down and finish the job of killing her, and Mitch and Garner decide to set a trap for the would-be-killer. Meanwhile, Eddie takes Shauni away from the stress of life guarding to a romantic weekend alone together aboard a boat he plans to buy at the local marina, while Harvey attempts to woo the other victim of the fisherman.
