Episode 6 - S3.E6

There are many reasons why the thousands of yellow-wellied volunteers first joined up, but they all share a common desire to help those in trouble. At Anstruther station in Scotland, one of their newest helms, George, takes charge for his first shout to a serious medical evacuation. A woman has slipped on one of the most notorious parts of the station's patch, the Chain Walk, where walkers have to negotiate steep cliffs while hanging on to chains hammered into the rock. On the north coast of Devon, the crew at Appledore station make a life-or-death dash to rescue two teenagers caught in a cave being flooded by the tide and pounded by waves, but arriving at the scene they discover that saving the young couple will mean putting themselves in danger. And when Storm Henry hits the British Isles and has shipping running for safe harbours, a cargo ship loses all power and is left at the mercy of the waves and 90-mile-an-hour winds. As she drifts inexorably towards the rugged cliffs of north Devon, two lifeboats are launched but even with their combined power they face a losing battle trying to tow the huge ship out of harm's way
