Perri rescues someone from the surf, only to discover that he's an adrenalin junkie who's risked both their lives to seek attention. She's hailed as a hero but is so traumatised that she vows never to rescue anyone again. It's Matt who gives her the confidence to go back on patrol. He teaches her some self-defence techniques so she won't have to risk her own life to save someone else's. (thetvdb.com)
