King Arthur desperately needs a haircut and because the royal barber is away, he foolishly accepts Sir Gads' offer to do the job. The result is a disaster, of course, so he turns to Merlin for help. Merlin's quick solution is a 'turn back time' spell, so that Arthur can return to the hour just before Sir Gads wreaked havoc on his hair. However, Sir Gads intervenes once more, and King Arthur finds himself unexpectedly in the present day instead. Trapped in the future, Sir Gads must find a way to help Arthur and himself return to mediaeval times. Knowing Sir Gadabout as we do, it's not going to be easy . . .
