Things are getting too hot in New York City for "Joker" Finnigan and his gang, so they decide to move their activities to London. There, Inspector Gary of Scotland Yard is keeping a polite eye on them since "Joker" is planning a big robbery of a large department store, known as the House of a Thousand Windows. "Joker" forces an American actor named Riley to impersonate Mr. Sherwood, the store owner, as Riley and Mr. Sherwood are identical in appearance. Ronald Martin, store employee and nephew of Sherwood, is also fooled, but he is distracted by the romance he is having with another store employee, Joan.
