"The documentary series about the maritime rescue services returns. The RNLI beach lifeguards in Cornwall are joined by two new teams - the crew of Coastguard helicopter India Juliet, and the RNLI lifeboat volunteers in Weymouth. India Juliet is scrambled to a trawler with a seriously injured crewman on board. The inshore lifeboat in Weymouth rushes to rescue two boys clinging to rocks. On the beach, the lifeguards have minutes to save a surfer found floating face down in the sea."
