Colonel Fairfax has been falsely accused of sorcery by a jealous relative who covets his estates and money. The Colonel is condemned to death for his 'crime' and waits in the Tower of London for his execution. Fate, however, steps in - in the form of Sergeant Meryll (who owes his life to Colonel Fairfax) and Elsie Maynard, a beautiful strolling singer who has just arrived at the Tower to entertain the people in the company of a strolling jester, Jack Point.
