Documentary series about a group of trawler fishermen in Peterhead, Scotland. Faced with ominous weather warnings, Sandy Watt must decide whether to brave violent storms or head for the safety of the harbour. Two much larger boats, the trawlers Starlight and Starlight Rays, hunt as a pair. Their skippers and crews must have complete trust in each other's skill and judgement - when casting their nets on perilous seas the trawlers come within a stone's throw of each other. One wrong move could result in catastrophe.
