Context: An eastern cult (a parody of the Thuggee cult) is about to sacrifice a woman to the goddess Kaili. Just as she is about to be killed, the high priestess of the cult, Ahme, notices that she is not wearing the sacrificial ring. Ringo Starr, drummer of the Beatles, has and is wearing it; it was secretly sent to him by the victim in a fan letter. Determined to retrieve the ring and sacrifice the woman, the great Swami Clang, Ahme, and several cult members including Bhuta, leave for London. After several failed attempts to steal the ring, they confront the Beatles in an Indian restaurant. Ringo learns that if he does not return the ring soon, he will become the next sacrifice. Ringo then discovers that the ring is stuck on his finger. The Beatles go to a jeweller to remove the ring, but the tools he uses all break. They then go to a mad scientist, Foot, and his assistant Algernon. In a lab full of British-made equipment, they attempt to expand the ring's molecules so it can slide off Ringo's finger. But the machines only manage to remove all his other rings. Astonished that his equipment has no effect on the ring, Foot decides that he, too, must have it. While they bumble with trying to get a laser together, Ahme crashes the lab and holds the scientists at gunpoint while she lets the Beatles escape. Back home, Ahme tells the group that her sister's time has passed and she is now out of danger and Ringo is now the sacrificial victim. She prepares a special solution intended to shrink Ringo's finger so she can get the ring off. But then Clang and his henchmen crash the house, causing Ahme to drop the syringe on Paul's leg. While a shrunken Paul hides in an ashtray, the cult attack the other Beatles and pour red paint on Ringo (as part of the sacrifice). Foot and Algernon come in, shoots a warning shot with his Webley and scares the cult away, Ahme in tow. Paul unshrinks and John subsequently starts to swing a lamp at Foot who tries to shoot him, but his gun misfires. Blaming this on the fact that the gun is British made, Foot retreats. The boys are left to sort things out. The band flees to the Austrian Alps for refuge but both thugs and Foot follow in pursuit. The Beatles practice skiing, then participate in a game of curling. Foot and Algernon booby-trap one of the curling stones with a bomb; George sees the "fiendish thingy" and tells everyone to run. The bomb eventually goes off after a delay, creating a big hole in the ice from which a Channel swimmer (Mal Evans) emerges and asks directions to the White Cliffs of Dover. The boys ski down a slope fleeing from Clang, directed by Ahme, who then misdirects Clang to the take-off ramp for a Ski jumping contest. Clang is the winner, and is forced to the winners' platform to receive a gold medal. The group escapes back to England and they ask for "protection" from Scotland Yard; and get it in the form of a cowardly Inspector (Cargill). After being attacked while recording in the middle of Salisbury Plain surrounded by the British Army, they hide in "A Well Known Palace" (Buckingham Palace) until they are almost captured by Foot. While on a walk with the police, the group step into a small pub, where Clang is disguised as a barman. After being served beer, Ringo cannot pick his glass up from the table, so George tips it over, unknowingly opening a trapdoor to the cellar that Clang set up. Inside the cellar is a door with a broken knob, a broken ladder and a tiger. They go summon the Inspector who tells them to sing the "Ode to Joy" from Beethoven's 9th Symphony to the tiger in order to tame it; everyone inside and outside the pub joins in. The Beatles put out in the press that they're going to the Bahamas to throw the cult off their
