Kathy Berman (Scott Adkins), a highly skilled and martial artist, is about to enter the marriage hall with his favorite woman, Namiko (Mika Elbow), and usher in their love crystallization. One night, Casey is out shopping while Namiko, who is alone at home, is brutally murdered by the invaders. Unable to suppress the resentment and sadness in his heart, Cayce indulged in the spray of anger.
After this, he washes away his previous dust and carries his bags to the Koga dojo in Thailand to practice, but the pain of bereavement makes the Kongwu man unable to control his emotions, like a beast that can run wild at any time. One day, a Daoist friend in the dojo was killed, and the murderer committed the same crime as Namiko's murderer. From Nakahara's mouth, it is possible that all this is related to the fact that Goro (Sugata Toshi), who has a lot of ties with the dojo and is now the leader of the Golden Triangle generation of gangsters, is doing it. Burdened with a deep hatred, Casey is on the road again...
The film is typical of the revenge movie, the biggest highlight is Arkins' various wonderful slalom kicks, which completely continue its style in "The Ultimate Fighter". The play was fairly smooth, with a few whirlwind kicks and over-the-shoulder throws. Boss Wars Tiger Tail originally left wonderful to the Invisible Boss Battle.
