This fourth installment in the Kickboxer series takes you back into the world of Muy-Tai champ Tong Po.
David Sloan is framed by Tong Po for a murder he didn't commit and sent to prison. Whilst in prison, David learns that his wife has been kidnapped by Tong Po and is being held captive at his fortress in Mexico. The Feds release David allowing him to rescue his wife if he agrees to lead them to Tong Po's fortress.
David travels there under a new identity and enters Tong Po's championship tournament. He must fight his way through Po's tournament and bodyguards while searching for his wife. This time, David isn't only fighting for his life, he's fighting for his lovely wife and he's taking no prisoners.
