Three years after his loss to "Pretty" Ricky Conlan, Adonis Creed scores a string of victories, culminating in a victory over Danny "Stuntman" Wheeler to win the WBC World Heavyweight Championship. Now a worldwide star, Adonis proposes to his girlfriend, Bianca Taylor, who agrees to marry him. When Bianca suggests starting a new life together in Los Angeles, Adonis is reluctant to leave his life in Philadelphia behind. Meanwhile, Ivan Drago, a former Soviet boxer who killed Adonis' father, Apollo Creed, in the ring thirty-three years earlier, sees an opportunity to regain the glory that was taken from him as a result of his loss to Rocky Balboain Moscow later that same year by pitting his son, Viktor Drago (with the assistance of Buddy Marcelle, a promoter who has followed Viktor's career closely), against Adonis. When Rocky refuses to support Adonis's decision to accept Viktor's challenge, Adonis, feeling betrayed, decides to leave for Los Angeles.
