Episode 5 - S2.E5

Every day around the UK, an army of unpaid volunteers put their lives on the line to try and save complete strangers. Saving Lives at Sea tells the story of the ordinary men and women of the Royal National Lifeboat Institution (RNLI) who, across the country, are ready to launch their boats and race to the rescue within minutes of a cry for help - 24 hours a day, 365 days a year, whatever the weather. Using footage shot on crews' own cameras, this series takes us right into the heart of the action, capturing the unpredictable work of the RNLI in never-before-seen detail.

In south west Wales, the Tenby crew race to a kayaker with suspected back and neck injuries after being caught out by a freak wave. Neighbouring Cornish crews must join forces in an epic 11-hour battle to stop a 3,600-tonne coaster breaking up on the rocks. And the Dart and Salcombe crews are astonished to be paged to the biggest shout of their lives.
