In the 6th Godzilla movie, mysterious aliens from the Planet X ask earth’s people to help them save their world from the dreaded Ghidorah (aka “Monster Zero”) by letting them “borrow” Godzilla and Rodan. Monster mayhem ensues on Planet X, but it’s soon discovered that the aliens have other intentions for the monsters.

A humble and simple Takezo abandons his life as a knight errant. He’s sought as a teacher and vassal by Shogun, Japan’s most powerful clan leader. He’s also challenged to fight by the supremely confident and skilful Sasaki Kojiro. Takezo agrees to fight Kojiro in a year’s time but rejects Shogun’s patronage, choosing instead to live on the edge of a village, raising vegetables. He’s followed there by Otsu and later by Akemi, both in love with him. The year ends as Takezo assists the villagers against a band of brigands. He seeks Otsu’s forgiveness and accepts her love, then sets off across the water to Ganryu Island for his final contest.

Returning to their lord’s castle, samurai warriors Washizu and Miki are waylaid by a spirit who predicts their futures. When the first part of the spirit’s prophecy comes true, Washizu’s scheming wife, Asaji, presses him to speed up the rest of the spirit’s prophecy by murdering his lord and usurping his place. Director Akira Kurosawa’s resetting of William Shakespeare’s “Macbeth” in feudal Japan is one of his most acclaimed films.
