Every day in the seas around the UK and Ireland, an army of unpaid volunteers put their lives on the line to save those of others. This series tells the story of the ordinary men and women of the Royal National Lifeboat Institution (RNLI) who are ready to race to the rescue of those in trouble, 24 hours a day, 365 days a year, whatever the weather. Using footage shot on the crews' own cameras, this series takes the viewers into the heart of the action, capturing the unpredictable work of the RNLI in unique detail.

From hurricanes to blizzards, from rip currents to quicksand, every day lifeboat crews around the UK and Ireland take on all of the unpredictable conditions that mother nature throws at them. As storm Ophelia hits the British Isles, on the south east coast of Ireland the pagers of the Rosslare crew go off - a small yacht with three people on board is caught in one of the worst storms in living memory. In Devon, the crew at Appledore race an incoming tide to try and reach a man stuck fast in quicksand, while on the north coast of Cornwall the crew of St Agnes must battle through huge breaking waves to reach two young boys being swept out to sea in a deadly rip current.
