Years after Adonis Creed made a name for himself under Rocky Balboa's
mentorship, the young boxer becomes the Heavyweight Champion of the
World. While life is good with that victory and his marriage to Bianca,
trouble comes to Philadelphia when Ivan Drago, the Russian boxer who
killed Adonis' father, Apollo, arrives with his son, Viktor, to
challenge Adonis. Against Rocky's advice, Adonis accepts the challenge
without his mentor's participation and pays the price in a punishing
bout he wins only by a technicality. Now injured and demoralized, Adonis
cannot bring himself to back into the game, leaving his spirit and
title in jeopardy. Together, Adonis' family and Rocky must find a way to
rekindle Adonis' fighting spirit to face the future in whatever choice
he makes. Meanwhile, the Drago family have its own troubles trying to
regain the respect in their homeland that they lost at Rocky's hands as
they wonder whether is it truly worth it.
