The fourth installment in the series finds karate master Mr. Miyagi (Noriyuki "Pat" Morita) with a new pupil: 17-year-old firebrand Julie Pierce (Hilary Swank), the recently orphaned granddaughter of a war buddy. Mercilessly harassed by the Alpha Elite, a group of neo-fascist male classmates, Julie turns to Miyagi for help. His teachings instill a sense of self-worth and discipline in Julie -- and she'll need it to take on the Alpha leader!
