Charlie Kenton, a washed-up fighter who lost his chance at a title when 2000-pound, 8-foot-tall steel robots took over the ring. Now nothing but a small-time promoter, Charlie earns just enough money piecing together low-end bots from scrap metal to get from one underground boxing venue to the next. When Charlie hits rock bottom, he reluctantly teams up with his estranged son, Max, to build and train a championship contender. As the stakes in the brutal, no-holds-barred arena are raised, Charlie and Max, against all odds, get one last shot at a comeback.
