A dying man carrying a partial film with the secret of Project Quasimodo, a miniature atomic bomb, gives only one clue to finding the rest of the film: the name of Marvin Klump, inept car salesman. THRUSH agents Rodney Backstreet and Beirut capture Klump. Solo and Illya, with the aid of Klump's sister Heather, follow them first to the Alps, them back to the U.S.,where the answer to the puzzle lies in a cemetery.
