When it seems that his plans will be thwarted, Akuri issues orders for the death of Mary and her friends, but Jim and his pal return and rescue them. Akuri then kidnaps Mary and takes her to his apartment, but with the help of Akuri's wronged Japanese lover, Jim learns her whereabouts. He organizes a posse of American Legion locals and rescues Mary just as Akuri is about to murder her. Akuri's group is routed out.
