An English scientist runs away from a research center with an atomic bomb. In a letter sent to the British Prime Minister he threatens to blow up the center of London if the Government don't announce the end of any research in this field within a week. Special agents from Scotland Yard try to stop him, with help from the scientist's assistant future son-in-law to find and stop the mad man.
