Stockton, California. When two men meet in the gym - the ex-boxer Billy Tully and the novice Ernie Munger - their brief sparring session sets in motion their hidden fates, initiating young Munger into the 'company of men' and luring Tully back into training. 'Fat City' tells of their anxieties and hopes, their loves and losses, and the stubborn determination of their manager, Ruben Luna, who knows that even the most promising kid is likely to fall prey to some weakness.
