Simple Spymen

Two street musicians are dragged into the War Office for causing a disturbance of the peace in Whitehall. Unwittingly they utter a phrase which is the secret password for the day, and are mistaken for M15 agents in disguise. They are immediately signed up for a hazardous mission to intercept an atomic scientist when he arrives in Dover. Thereafter, they make endless attempts as different characters to gain access to the scientist's hotel and secure the formula for the British Government. They display courage, ingenuity, and more than lint of lunacy.
