description About

In the first episode, a retired nursery teacher gets herself into danger when attempting to rescue her two dogs after they became cut off by the rising tide. In Wales, one volunteer crew member is washed off a cliff into the sea trying to rescue a concussed spearfisherman, and, in Blackpool, a rescue in a force seven gale goes badly wrong, putting all three crew members' lives in jeopardy. When torrential floods hit Cumbria shortly before Christmas the volunteers are again on hand to try and rescue families trapped by the rising waters.
