The greatest underdog story of our time is back for one final round of the Academy Award-winning “Rocky” franchise, former heavyweight champion Rocky Balboa steps out of retirement and back into the ring, pitting himself against a new rival in a dramatically different era. After a virtual boxing match declares Rocky Balboa the victor over current champion Mason “The Line” Dixon, the legendary fighter’s passion and spirit are reignited. But when his desire to fight in small, regional competitions is trumped by promoters calling for a rematch of the cyber-fight, Balboa must weigh the mental and physical risks of a high profile exhibition match against his need to be in the ring.
