We investigate how a fisherman can survive an encounter with hungry sharks; discover if a body-boarder can get a drowning and unconscious surfer to shore; how a motoring mishap turns into an aquatic emergency; see a kite surfer dazed, drowning and dragged along desperate for air; learn that sea lions aren't as cute as they look and see a father and son dream team have a career ending nightmare. Plus, there are loads of clips from around the world illustrating just how deadly water can be.
