Fresh cod, mackerel, herring, and salmon caught off Norway's Arctic coast have one way to reach the rest of Europe on time: a 1,200-mile freight route through the mountains of Norway and Sweden. This film follows the specialized container train built for that job, tracking the refrigerated trailers that keep each catch at temperature through steep grades, ice, and tunnels where a delay of hours can mean spoiled cargo and lost contracts. Crews and engineers explain how the route is planned around weather windows and mechanical checks, and the cameras ride along through yards, switching points, and the exposed high-altitude stretches where the line is most vulnerable to snow and rockfall. The focus stays practical throughout: how a fishing catch becomes freight, how refrigeration units are monitored en route, and what happens when the schedule slips. It is a close look at the logistics behind a food supply chain most people never think about, built around the daily pressure of getting the day's catch to market before it stops being fresh.
