Twelve-year-old Dre Parker moves with his single mother from Detroit to unfamiliar Beijing, knowing neither the language nor the local customs. There he meets a Chinese girl named Mei Ying. However, in addition to her father, who disapproves of their friendship due to cultural prejudices, he faces a gang of bullies led by Chen, a master of kung fu. The only way to defeat him is to face the enemy at an upcoming grand martial arts tournament. A martial arts expert, Mr. Han, decides to help the boy.

We are reunited with Mr. Miyagi, a wise and experienced martial arts master from the island of Okinawa who once trained the talented young Daniel. This time, Mr. Miyagi takes a girl under his wing to raise and train her! His new student is the granddaughter of an American soldier who saved Miyagi’s life during World War II. Julie is struggling in school, doesn’t get along with her mother, has gotten mixed up in trouble with bullies, and has turned against the whole world. Miyagi will help Julie let go of her anger and teach her to put maximum power into her strikes. It won’t be easy for Julie, because in addition to her enemies—the school bullies—the young karateka will have to face their adult leader, the school coach, and the villain.
