Robin of Sherwood (1984)

The arrival in Sherwood of seven Templars, heading back to their church in Lincoln, and their gold crested banner is too much for a thief, Siward, to ignore. He steals the banner and runs into Robin and his men as he escapes. The Templars think that they are all together and after a brief altercation the Templars leave, with Much as a hostage. Now Robin and his men have to deal with seven of the most feared fighting men known to man, to rescue Much from their grasp.
