A creaky stage play is transformed by Powell into a cheap but splendidly atmospheric comedy thriller. Gordon Harker stars as a Cockney lighthouse-keeper who, with the aid of an insurance investigator (Hale) and a naval officer (Hunter), sees off a gang of wreckers intent on no good. The leader of the wreckers is one 'Dr Carey', the setting is Wales, and the climactic confrontation is intercut with a ship heading for the rocks. Any party, even the Welsh Nationalists, could interpret this allegory to their own ends.
