In this episode we look at a number of life and death situations as well as the on-going training regime the Marine Police undertake. We follow dive and chopper squads as they search for the body of a man washed into a swollen river in Tasmania's northwest. As well, we follow a squad on the Van Diemen as they head into the Southern Ocean to rescue a lone, round-the-world, Norwegian sailor. His motor has broken down and he's foundering in big seas with storms on the way.
