Quick recap
Rocky comes home from Moscow with brain damage and finds out he's broke: an accountant drained everything after Paulie signed over power of attorney. The family loses the mansion and moves back to the old neighborhood, and doctors bar Rocky from fighting. He reopens Mickey's gym and starts training Tommy Gunn, a raw young talent. Tommy rises to contender, but Rocky pours so much into him that he drifts away from his son, Robert, who's struggling at his new school. Promoter George Washington Duke lures Tommy away with money and a title shot. Tommy wins, but fans call him a paper champion for never facing Rocky. He punches Paulie, and the two of them fight in the street; Rocky wins and reconnects with his son.
