Returning with Daniel Larusso (Macchio) accompanies his wise and whimsical teacher Mr. Miyagi (Morita), to his ancestral home in Okinawa. For the boy, it's a journey to an exotic new world, offering new clues to his mentor's secret past. For Miyagi, it's an opportunity to see his father one last time and to rekindle a romance with his childhood sweetheart (Nobu McCarthy). But Miyagi's return also re-ignites a bitter feud with long-time enemy Sato (Danny Kamekona) - a feud that involves young Daniel in a brilliant collision of cultures and combat. Now, far away from the tournaments, the cheering crowds and the safety of home, Daniel will face his greatest challenge ever when teacher becomes student, and the price of honor is life itself.
