A series of mysterious deaths in a Welsh lighthouse lead locals to believe it is haunted. But the new keeper is sceptical.

Tod Slaughter goes about the countryside strangling everybody. His evil scheme is to destroy the family who wronged him. He has a secret lab complete with a torture chamber, featured in the films climax. Probably the most maniacal portrayal Tod ever gave.

BBC live outside broadcast from the Theatre Royal, Stratford, of Tod Slaughter’s production of his melodrama Spring-Heeled Jack.

The film stars Edmund Gwenn, who plays a chemist, whose son Lawrence (played by Barry MacKay) is attacked on a train. He appears to have shot the man.
