Plot Summary:
Years after proving himself in the ring, Dre Parker (Jaden Smith) has grown into a disciplined young man under the mentorship of Mr. Han (Jackie Chan). But when Dre’s family relocates again—this time to Japan, the birthplace of karate—he finds himself at the center of a cultural clash far beyond anything he’s faced before.

In Tokyo, Dre struggles to adapt to new traditions while training in a dojo that values honor above victory. There, he encounters a rival student from a powerful karate family, whose lineage ties back to ancient martial arts rivalries. What begins as schoolyard intimidation escalates into a high-stakes international martial arts tournament, where Dre must not only defend himself, but prove that karate is more than just fighting—it’s balance, respect, and heart.

Meanwhile, Mr. Han faces his own ghosts from the past when an old adversary resurfaces, testing both mentor and student in ways that go beyond the mat.
