Robin is determined to get hold of the Great Pact of Nottingham, but when a lovelorn Knight begs the outlaws to help him save his girl, Robin decides he'll use the Knight's silver to locate where the Sheriff's treasure, including the Pact, is hidden. But with Allan A Dale now firmly on the dark side and leaking the outlaws' secrets to Gisborne, Robin realises he must act quickly to save Marian. Worse still, Edward has his own agenda for the Pact, with tragic and life-changing consequences for Marian. (BBC)
