Robin of Sherwood - Season 3 - Eps 10: The Pretender
Taking up with a 12 year old French princess, King John has annulled his marriage to Queen Hadwisa, who vows revenge against her former husband and the new queen, Isabella. Her plan is to have Isabella murdered while on a pilgrimage and make it appear to have been done by Robin Hood. Hadwisa's family believe they have enough support among the barons to depose King John and replace him with a new young man who claims to be Arthur of Brittany, John's nephew. While Arthur infiltrates the outlaw band, Gisburne becomes involved in the plot. Gisburne is only too eager to advance his position and finish off Robin Hood all at the same time. The Sheriff, however knows that "if Queen Isabella dies, we shall ALL hang," but gravely ill from a dog bite, he is unable to stop Gisburne.

Synopsis
Robin of Sherwood was a British television series, based on the legend of Robin Hood. Created by Richard Carpenter, it was produced by HTV in association with Goldcrest, and ran from 1984 to 1986 on the ITV network. In America it was retitled Robin Hood and shown on the premium cable TV channel Showtime and on PBS. The show starred Michael Praed and Jason Connery as two different incarnations of the title character. Unlike previous adaptations of the Robin Hood legend, Robin of Sherwood combined a gritty, authentic production design with elements of real-life history, 20th century fiction, and pagan myth. The series is also notable for its haunting title music by Clannad, which won a BAFTA award.
