On Ireland's north west coast, the crew at Bundoran race to the rescue of a teenage girl who has been swept out to sea by a rip current. In Portishead, north Somerset, a man has suffered serious chest injuries after falling 30 feet from a cliff and needs to be rushed to hospital. Across the Bristol Channel in Porthcawl, a missing dog sends the crew on a wild goose chase. And in the fishing town of Fraserburgh, on the north east coast of Scotland, the crew search for a local fisherman who's failed to return to harbour.
