A historian gives a brief overview of medieval England. In a miscommunication between the actors and the narrator, a Scandinavian village appears, with Finnish villagers along with the Mayor of the country on his fort singing the "Fisch Schlapping Song." Ten men grab tiny fish and lightly slap the women in the face with them. After a couple of slaps, the women pull out much larger fish and slap the men in return with great force, making the men fall flat on the floor. The villagers continue to sing and dance. Then, two women slap the mayor hard in the face with enormous fish, both having huge smiles on their faces while slapping him. Because both women slapped him at the same time with so much force, the mayor falls flat on the floor, then leaves the stage. His fort is then taken over by one of the women who slapped him. The villagers continue to sing and dance. The Historian returns, irritated, and tells the frolicking Finns that he was talking about England, not Finland. The scene immediately goes to a dreary, dark village with penitent monks in hooded robes chanting Latin. King Arthur travels the land with his servant Patsy, who follows him around banging two coconut shells together to make the sound of a horse's hooves as Arthur "rides" before him, trying to recruit Knights of the Round Table to join him in Camelot. He encounters a pair of sentries who are more interested in debating whether two swallows could successfully carry a coconut than in listening to the king.
Sir Robin, a collector of plague victims, and Lancelot, a large, handsome and incredibly violent man, meet as Lancelot attempts to dispose of the sickly Not Dead Fred. They agree to become Knights of the Round Table together, Lancelot for the fighting, and Robin for the singing and the dancing.
Arthur attempts to convince a peasant named Dennis Galahad that he, Arthur, is king of England because the Lady of the Lake gave him Excalibur, the sword given only to the man fit to rule England. However, Dennis and his mother, Mrs Galahad, are political radicals and deny that any king who has not been elected by the people has any legitimate right to rule over them. To settle the issue, Arthur has the Lady Of The Lake and her Laker Girls appear to turn Dennis into a knight. Cheered on by the girls, the Lady Of The Lake turns Dennis into Sir Galahad and together, they sing a generic Broadway love song, complete with chandelier. They are joined by Sir Robin and Sir Lancelot, and together with Sir Bedevere and "the aptly named" Sir Not-Appearing-In-This-Show (a knight resembling Don Quixote, who promptly apologises and leaves), they make up the Knights of the Round Table.
The five knights gather in Camelot, a deliberately anachronistic place resembling Las Vegas's Camelot-inspired Excalibur resort, complete with showgirls, oversized dice and the Lady of the Lake headlining the Castle in full Cher get-up. In the midst of their revelry, they are contacted by God who tells them to locate the Holy Grail. Urged on by the Lady Of The Lake, the Knights set off. They travel throughout the land until they reach a castle, only to be viciously taunted by lewd French soldiers. They attempt to retaliate by sending them a large wooden rabbit in the style of the Trojan Horse; however, they realise after the fact that it was not as simple as leaving the rabbit and walking away – they should have hidden inside it. Defeated, they leave in a hurry when the French begin taunting them again, sending cancan dancers after them and throwing barnyard animals including cows at them. Arthur and his followers manage to run into the safety of the wings before the French catapult the Trojan Rabbit at them.
Sir Robin and his minstrels follow King Arthur and Patsy into a "dark and very expensive forest", where they are separated. King Arthur meets the terrifying but silly Knights who say Ni, who demand a shrubbery. King Arthur despairs of finding one, but Patsy cheers him up and they find a shrubbery shortly after.
Sir Robin, after wandering the forest for some time with his minstrels, encounters The Black Knight, who scares him off, but King Arthur, who happens on the scene, more or less defeats him by cutting off both his arms and legs, impaling his still-alive torso on a door, and leaving to give the Knights their shrubbery. The Knights accept it, but next demand that King Arthur put on a musical and bring it to Broadway (in the United Kingdom, this became a West End musical; on the tour, they must put on a "Broadway musical"), implying that it need only be Broadway-style, "but not an Andrew Lloyd Webber". The mere mention of his name causes everyone to cover their ears and scream in pain. Sir Robin, who has found Arthur by this point, insists that it would be impossible for them to accomplish this next task, since you need Jews for a successful Broadway (or celebrities for the West End) musical , and proves his point in a wild production number filled with Fiddler on the Roof parodies, including a bottle dance like the one in Fiddler On The Roof, with Grails instead of bottles. King Arthur and Patsy promptly set off in search of Jews.
While the Lady Of The Lake laments her lack of stage time, Sir Lancelot receives a letter from what he assumes is a young damsel in distress. He is very surprised to find that the "damsel" is actually an embarrassingly effeminate young man named Prince Herbert whose overbearing, music-hating father, the King of Swamp Castle, is forcing him into an arranged marriage. As Herbert is asking Lancelot to help him escape, the King of Swamp Castle cuts the rope that he is using to climb out of the window, and Herbert falls to his apparent death. Lancelot is a bit puzzled at the king's actions, but it is revealed that Herbert was saved at the last minute by Lancelot's sidekick, Concorde. The King asks his son how he was saved, exactly, to which Herbert replies happily with a song. But the king charges at his son with a spear, preparing to kill him. Lancelot steps in to save him, then gives a tearful, heartfelt speech about sensitivity to the king on Herbert's behalf, and Lancelot is outed as a homosexual in the process, an announcement celebrated in a wild disco number.
King Arthur begins to give up hope of ever putting on the Broadway musical and laments that he is alone, even though Patsy has been with him the entire time. The Lady Of The Lake appears and tells Arthur that he and the Knights have been in a Broadway musical all along. Patsy also reveals he is half Jewish, but didn't want to say anything to Arthur because "that's not really the sort of thing you say to a heavily armed Christian." All that's left is for King Arthur to find the Grail and marry someone. After picking up on some not-too-subtle hints, Arthur decides to marry the Lady Of The Lake after he finds the Grail.
Reunited with his Knights, Arthur meets Tim the Enchanter who warns them of the danger of a killer rabbit. When the rabbit bites a knight's head off, Arthur uses the Holy Hand Grenade of Antioch against it, knocking down a nearby hill and revealing that the "evil rabbit" was actually a puppet controlled by a surprised puppeteer. A large stone block showing a combination of letters and numbers is also revealed. (The letters are based on the seat numbering system used by each theatre.) After pondering the final clue, Arthur admits that they're "a bit stumped with the clue thing" and asks God to "give them a hand". A large hand points to the audience and Arthur realises that the letters and numbers refer to a seat number in the audience. The grail is "found" (with some sleight of hand) under the seat and the person sitting in the seat is rewarded with a small trophy and a polaroid photo. Arthur marries the Lady of the Lake, who reveals that her name is Guinevere; Lancelot marries Herbert (who finally has a chance to sing); and Sir Robin decides to pursue a career in musical theatre.
