Jean Claude Van Damme kicks up his heels once again in this action film. Van Damme plays Kurt Sloane, the brother of American kickboxing champion Eric Sloane (Dennis Alexio). Having bested the best in the United States, Eric takes off to Bangkok with little brother Kurt to defeat the kickboxing champion of Thailand. However, while Eric wins the fight, his career is finished for good when his opponent, the malicious Tong Po (Michel Qissi) breaks his spine after the final bell sounds, putting Eric permanently in a wheelchair. Kurt learns the sport of kickboxing himself, so he can get in the ring and teach the Thai champ a lesson. An old man who is a master at kickboxing, instructs Kurt in the brutal art, along with gentle bromides of Zen philosophy and spiritual peace. Kurt finally becomes a pro and lines up a match with Tong Po, but to insure victory, Tong Po's cohorts rape Kurt's girlfriend, kidnap his crippled brother, and even kill his dog. But Kurt is unbowed and is ready for the champ to meet his match.
