However, after winning his final match, he runs afoul of powerful crime lord Ba Rau, who ruthlessly retaliates in a cruel attack on Phi’s wife. Blinded by grief and rage, Phi vows revenge and tracks Ba Rau across Vietnam—right into the heart of a criminal enterprise that has been terrorizing local villagers for years.
