Former Royal Navy officer Mike Nicholls (Nick Berry, Heartbeat) takes the job of harbourmaster at Bridehaven, the town where he grew up, in the hopes that it will help put his past behind him. Along with WPC Melanie Rush (Tina Hobley, Holby City), they keep the passing parade of smugglers, errant yachtsmen, and foolish tourists under control, even as they develop strong feelings for each other.
