 While escaping from the police, English highwayman Dick Turpin (Louis Hayward) meets Joyce Greene (Patricia Medina.) They marry and Turpin settles down to respectability until his mother-in-law (Barbara Brown) discovers he is the famous outlaw. He resumes his old calling along with Tom King (Tom Tully) and uncovers evidence that proves his arch-enemy, Lord Willoughby (Alan Mowbray), is plotting against King George (Ivan Triesault). He is betrayed by Cecile (Suzanne Dalbert), a jealous accomplice, and to protect his wife, Turpin rides the 200 miles from London to York.
