American kickboxing champion Eric Sloan (Dennis Alexio) travels with his brother Kurt (Jean-Claude van Damme) to Thailand to fight local champion Tong Po (Michelle Kissi). Immediately after the fight begins, it becomes clear that Tong Po is much stronger than his opponent. However, Eric refuses to stop fighting and ends up in a wheelchair. Since Tong Po did not stop beating him after the fight was officially stopped, Kurt decides to take revenge on him. He finds a famous Thai boxing teacher (Dennis Chan) and begins training for a rematch.
