Despite his hobby of fighting battles with toy soldiers, Edward is a mild person and he is about to experience an evening he will never forget. He works at the Continental Telephone Exchange where his pompous brother-in-law is his supervisor. Edward often 'chats up' women operators in various exchanges. These affairs by proxy suddenly explode in his face when four glamorous females travel to London to compete in the Miss Europhone Contest and arrive at this home anxious to meet the flirtatious Mr London in the flesh. Hilarious complications ensue as Edward strives to conceal his telephonic peccadilloes from his wife, his appalling mother-in-law and his lodger, an ardent curate.
