Even on an apparently quiet day, the life guards are flat out with serial rescues. A rescued Korean student shows that water in the lungs can bother you for a long time. A Britton learns fishing from the rocks can lead to a terrible fall. Kyle demonstrates a Hawaiian cross between Polynesian rowing and modern board surfing. When he's shown a suspicious canister, his safety measures are substandard. Kerrbox calls for professional help - the police and bomb squad arrive, and so ever more beach is closed off. The boys miss out on most of Valentine's evening to assist them.
