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 us into the heart of the action, capturing the unpredictable work of the RNLI in unique detail.

From first timers at sea to salty old skippers, the wrong conditions can catch anyone off their guard leaving them in need of rescuing. On the east coast of Ireland, the crew of Courtown's inshore lifeboat face one of their most challenging shouts ever - in deep water they must keep a teenage girl with suspected spinal injuries immobile and afloat for 40 minutes, knowing any movement could leave her paralysed for life. Meanwhile on the English Riviera in Devon, the Torbay crew have just minutes to find a capsized kayaker before she is dashed against the rocks, and in Dartmouth, an 81-year-old sailor, fallen overboard in the middle of the night, is left clinging to a rope for his life.
