King Arthur (Graham Chapman) and his Knights of the Round Table (John Cleese, Eric Idle, Terry Jones and Michael Palin) on the trail of the elusive Holy Grail, encountering many nasty and long-winded characters (John Cleese, Eric Idle, Terry Jones and Michael Palin) on the way. Who can forget the quest for a shrubbery to placate the fearsome Knights who say 'Ni', the fearless, and limbless, Black Knight, the mysterious wizard Tim and the horrific White Rabbit, with the big pointy teeth.
