In Kickboxer we saw how Kurt Sloan (Jean Claude Van Damme) was victorious in his fight against the brutal Tong Po (Michel Qissi). But Tong Po is not so easily defeated and in a burst of rage guns down the champion as he prepares to leave Thailand. For Tong Po's manager Sangha this is a disgrace that he cannot bear for the kickboxing championship can't be regained unless he can goad Kurt's younger brother David (Sasha Mitchell) into the ring to fight Tong Po for the title. Under the watchful eye of his brother's trainer Xian (Dennis Chan) he must enter the ring and face the lethal kickboxing skills of Tong Po risking everything including his life to avenge the insane violence of the deadly Thai fighter.
