Episode 8

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 Ilfracombe, a father and son find themselves in danger after jumping in to rescue a drowning dog. The Minehead crew must scour the cliffs and shoreline after a young woman goes missing in a distressed state. And when they're paged to a man seen entering the Thames, the Tower crew face the possibility they may not find him in time.
