The wicked Norman Lord Rupert uses his son Gregory to wage a campaign of terror to pressurise the Saxon farmers into handing over their land to him. The plan proceeds until he takes over some property of Little John's brother, when Robin and his band arrive and decide to intervene to organise some resistance. In the ensuing fight Robin captures Gregory, but Lord Rupert counters by capturing Joshua, the son of the local judge, Marcus of Brandwyn. So Robin now has to rescue Joshua from Lord Rupert's castle.
