Thompson is an American physicist living in England who is called on to locate a secret agent working at his research station. Thompson goes undercover to learn the spy's identity and, with the help of Aubrey, his wife and assistant, digs up some answers. Loder, an army major, then comes
in to help round up the perpetrator, who will surprise the viewer. Rather tired overall, though.
