In the early 1980s, Reese Sharp (Sylvester Stallone Sylvester Stallone) and Kidd McTang (Robert de Niro Robert De Niro) from Pittsburgh staged two classic boxing fights that captivated the world. But shortly after the 1984 game, the heyday Rizze suddenly announced his retirement, and soon spent all his property and became an ordinary worker who sold his labor for a living. In contrast, Kidd continues to decline, endorsing all kinds of unfashionable advertisements and passing the time by selling his mouth. One day in 2014, Dante Jr. (Mason Mackie), the son of Rizzer's then manager, came to the door and invited him to participate in the production of a game. Unexpectedly, at the production site, Reitzer and the unsolicited Kidd got into a big fight, the video of the two men fighting went viral on the Internet, and their 30th anniversary battle was put back on the agenda. It's just that the two, who have already passed their peak state, can cope with the erosion of time, put aside their grievances, and complete this belated showdown.
