30 years ago, Billy 'The Kid' McDonnen (De Niro) and Henry 'Razor' Sharp (Stallone) were boxing rivals but Razor decided to leave the ring for good the night before they were due to battle it out for the championship, which ultimately put an end to both their careers. With each of them having achieved a win in their previous two matches, the pair now have the opportunity to face each other a third and final time. They each start up a training regime in preparation for the match but at their age, both The Kid and Razor aren't as fit as they once were. Can either of them prove they still have what it takes to win? The film also stars Kevin Hart, Alan Arkin, Kim Basinger and Jon Bernthal.
