Comedy in which a bungling railway worker is given the job of stationmaster at a rundown station in rural Ireland, where his sidekicks are a toothless old gaffer and a portly young loudmouth. Hilarious adventures ensue, including a locomotive chase after gunrunners make off with a train.

A young Scottish RAF gunner is debriefed by French officials about his escape from occupied territory, and in particular one person who may or may not have been a German agent.
