Cedric a novice knight is getting combat training from Sir Lancelot.
Cedric's prospective bride comes to see him and tells him that the dastardly Torwald of the Black Castle has kidnapped his prospective father in law.
Cedric goes off to do combat with Torwald who has a fearsome reputation as a fighter. Sir Lancelot races off to fight Torwald himself and soften him up first for Cedric knowing that the novice knight is not yet good enough for combat.
Lancelot finds that Torwald is a bit of a cheat. He pays others to pretend to be him and fight on his behalf. Then there is also his knight Magnus and his crossbow at the ready if things get a bit too tricky.
It is all a bit routine plot wise by now. The opening did have the other knights in the roundtable. There was no need for Cedric to go on his own. The story was a tad silly with Brian ordered to make sure that Cedric gets delayed.
Derry Nesbitt is Magnus. Michael Blakemore who plays Cedric is a multi Tony award winning theatre director.
