After 30 years of living in a box buried six feet underground, the so-called Devil Claw breaks from his grave and takes over the body of a monk (Yuen Yat Chor), whom he uses to get revenge on the men who buried him decades before. With supernatural abilities to fend off blows, become invisible and use his extremities like swords, the reincarnated corpse is a vengeful force to be reckoned with, making for a classic kung fu flick that packs a punch.

After a night of trying to drink himself out of his depression, Stone receives a vision of Lee instructing him to investigate the circumstances of master's death. Stone soon finds that Lee was the victim of foul play, and quickly puts into action his plan for bringing the murderers to justice.
