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.

The Baronets of Ruddigore have been cursed by a witch. Each Baronet, in his turn, must commit a crime a day - or die in torture. To escape his dreadful fate, the latest Baronet, Sir Ruthven Murgatroyd, disguises himself as Robin Oakapple, a farmer. Only two people know his true identity - his faithful servant, Old Adam Goodheart, and his adopted brother, Richard Dauntless, a seaman. Robin Oakapple is in love with the beautiful Rose Maybud and wants to marry her - but his future plans appear doomed when his true identity is revealed.
