Plot

Jeff Sanders (Jeff Speakman) is an expert Kenpō student and master of his craft. After losing his mother as a child, he became an outcast and frequently lashed out at his family and society in an attempt to assuage his anger. His father, Captain Sanders (Beau Starr), gained the idea from a mutual friend, Kim (Mako), to enroll Jeff in a Kenpō school to better manage his rage and feelings. However, he lost his temper with a football player who punched his younger brother, and almost kills him. Displeased with this event, Jeff's father forced him to move out of their home. Jeff, now estranged from his family and living alone, continued with his courses in Kenpo and eventually adopted Kim as a mentor and father figure.
