A priest, a woodcutter, and a peasant take refuge from a downpour beneath a ruined gate in 12th-century Japan. The priest and the woodcutter, each looking stricken, discuss the trial of a notorious bandit for rape and murder. As the retelling of the trial unfolds, the participants in the crime -- the bandit (Toshiro Mifune), the rape victim (Machiko Kyo), and the murdered man (Masayuki Mori) -- tell their plausible though completely contradictory versions of the story.
