Laughlin's "Billy Jack" character was introduced to movie audiences in this violent, vigilante biker film, considered by some the best of the genre. Half-breed Laughlin witesses a gang of violent bikers, led by Slate, tormenting innocent citizens. He steps in to stop the bullies, only to
find his own violent response gets him in trouble with the law. Though he's baffled by the twisted legal system, he continues to battle the bikes, eventually killing Slate before being slain by a deputy. Laughlin directed under his T.C. Frank pseudonym, and four years later his character was
resurrected in the inane cult classic BILLY JACK, followed by two sequels.
