Premiered in July 1931, Ippon-gatana Dohyo-iri centres around a failed sumo wrestler called Mohei. He is aided by a prostitute (although Mohei doesn't know) called Otsuta, who gives him money to visit his mother's grave. Mohei resolves to become a reach the top of the sumo ranks and to invite Otsuta to watch him perform the ring-entering ceremony. Fast forward ten years and Mohei is an abject failure in the sumo world, but is a fairly successful gangster. He has never forgotten the kindness of Otsuta and seeks her out to repay the money. He finds her living poor lifestyle with a daughter and husband being pursued by gamblers after he cheated them. Otsuta doesn't recognize Mohei at first, until he uses some sumo moves to fight the gangsters. Mohei is able to repay her kindness and let her family start a new life. 83 min, Region Code:All NTSC.
