Episode 7

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.

When a climber falls in a remote cave on the Gower Peninsula, the Mumbles crew are called in to search and rescue. In Portreath, lifeguards battle to save a teenager who is determined to surf despite red flag warnings. And on the Isle of Wight, the Yarmouth crew must locate a man in the water amongst over a thousand boats competing in the Round the Island Race.
