"Rocky Balboa" is the next story in the saga of Philadelphia boxer Rocky Balboa, one of Hollywood's most beloved characters.
Long since retired, and with his beloved Adrian passed away and his grown son too busy to spend time with him, Philadelphia's favorite boxer is a lonely man. Running a small restaurant in his old neighborhood, Rocky passes the time by recounting stories of his glory days to his patrons.
To keep himself busy and in shape, he decides to step back into the ring against a few small-time boxers in local gyms. When an ESPN sports show runs a simulated fight between Balboa and the current champ, Mason "The Line" Dixon, Balboa wins, prompting a resurgence of interest in his illustrious career.
Presented with the opportunity to fight one last exhibition fight, Rocky accepts the challenge, despite the protests of his friends and family. Facing a powerful champion, personal tragedy and ultimately his own doubts, Rocky steps into the ring one last time to prove that he still has the heart of a champion.
