 While isolated from his relatives, he one day faces the mysterious stranger who turns out to be his long-lost rejected twin, Sutekichi (again Motoki).Bent on revenge, Sutekichi throws him into the garden's well and takes over his life and his wife.The final conflict between the two brothers is realized when Yukio, forced into an animalistic existence in the well, reemerges, prompting the fratricidal fight for the love of the same woman, since it turns out (while he takes over Yukio's role) that Rin had actually once been Sutekichi's lover.
