Driving by his powers, Lee, an active member at the temple, has been chosen to take part in the tournament that takes place in the island, owned by an evil corrupted man, Han, who has illegal works and uses these competition to hide his reality of trading in drugs, but upon his arrival at the island, he finds out that Han is the killer of his sister, the thing that makes his rage and drives him to seek revenge.
As in even the very best Kung Fu movies, mayhem ensues, especially once hundreds of fighting champions storm the island in an out-of-control melee that Lee walks through with complete cold discipline.
The acting is wooden and the sound effects are even worse (especially in terms of voice dubbing). But the fight scenes are excellent especially in reference to Bruce Lee.
