The fourth installment of the successful Karate Kid series, which has grossed over $300 million worldwide, stars Academy Award® winner Hilary Swank as a troubled teenager. Since the death of her parents, 17-year-old Julie Pierce (Swank) has directed her anger at all the wrong places. She's angry at the grandmother who can no longer raise her, at the violent all-male "posse" that harasses her at school, and angry and confused with herself as she struggles to become a woman. But enigmatic karate teacher Mr. Miyagi (Pat Morita) sees in Julie a strength she could never recognize in herself. To repay a debt to Julie's grandfather, who saved his life in World War II, Mr. Miyagi takes Julie on an odyssey that allows the girl to reclaim not only the strength to defeat her foes, but the strength to be herself.
