Sasha Mitchell (“Kickboxer 2&3”) triumphanty returns to the ring as David Sloan, fighting not just for his survival, but for his beautiful wife, who has become the sexual captive of the despicable world champion, Tong Po. Framed, forgotten and furious, Sloan has been wasting away in prison, but the Feds agree to release him, if he will lead them inside Tong Po’s impenetrable Mexican fortress, protected by its deadly guards and adorned by its sexual slaves. Sloan reluctantly teams up with a female fighter to gain entry into Po’s tournament of champions, a savage battle where winner takes all – and to Sloan – that means everything!

One year after the events of “Kickboxer: Vengeance”, Kurt Sloan has vowed never to return to Thailand. However, while gearing up for a MMA title shot, he finds himself sedated and forced back into Thailand, this time in prison. He is there because the ones responsible want him to face a 6’8″ 400 lbs. beast named Mongkut and in return for the fight, Kurt will get two million dollars and his freedom back. Kurt at first refuses, in which a bounty is placed on his head as a way to force him to face Mongkut. Kurt soon learns he will have no other choice and will undergo his most rigorous training yet under some unexpected mentors in order to face Mongkut in hopes to regain his freedom.
