Plot

To escape both his bank manager and his overbearing wife Lady Histeria, Prancelot decides to join the crusades. He is dismayed when he learns that Histeria intends to accompany him and eventually the entire household – including the children Sim and Sue, the miserly majordomo Girth, a cockney minstrel (who is also the show's narrator) and several serfs – set sail for adventure. They repeatedly fall foul of the dastardly Count Otto "The Blot" but always escape by some contrivance of Sir Prancelot himself. After many unlikely adventures they arrive in the Holy Land to discover they are 50 years too late. After a final showdown with Count Otto they return to England in a rocket ship also invented by Sir Prancelot.
