CIRCLE OF DANGER stars Ray Milland as an American at large in London, Wales and Scotland. During World War 2, Milland's brother had died in a commando raid. The details of his death were somewhat murky, and Milland would like to know the truth. The truth is murder in every sense of the word, though rather disappointingly, Milland himself is never in any peril. While CIRCLE OF DANGER was produced by longtime Hitchcock associate Joan Harrison, the Master's touch is noticeably absent.
