"Ukigumo" covers a considerable span of time and numerous locations. It tells the story of a young woman (Hideko Takamine) who served in Japan's forest service in Indochina during WW2, and fell in love with a (married) co-worker (Masayuki Mori) while there. After the war, she returns to Japan, completely impoverished, and finds her lover (more or less) comfortably re-established in his family and uninterested in fulfilling the idle promises he made during the war. While Mori is only willing to dally half-heartedly with her (as well as younger prettier women), Takamine remains obsessed with him. Takamine and Mori do a fine job. I found the story effective enough, albeit a bit overly melodramatic. Not my favorite Naruse film, but very much worth seeing.
