An intimate documentary on the punched and the punchless, the knocked-down and the knocked-out, Unchain reveals as much about Japanese drop-out society as it does about its ostensible focus, boxing. Its erratic, rumbling epicenter is Unchain Kaji, a part-time boxer and full-time troublestarter who takes his name from the Ray Charles song "Unchain My Heart." His record is a proud litany of failure: many losses, most by knock-out, one draw, no wins. Retiring after nerve paralysis, he changes his name to Half Wit, starts random barfights, fronts a punk rock band, and, finally snapping, pours yellow paint over his head and attacks a job center armed only with a wrench and a hammer. Interviewing his few remaining friends, all boxers, all with careers spiraling downward, Unchain outlines life on the wrong side of the winners column, where the fight to "unchain my heart" proves the only one worth living.-Jason Sanders
