After the Liangshan heroes are schemed against by the imperial court and suffer heavy losses, the surviving heroes lose heart and eventually make their way to Siam. In this foreign land, they endure hardship and rebuild their strength. They not only secure a foothold, but also assemble an elite army.
When they hear that the Jin troops are marching south and the people of the Central Plains are plunged into misery, the old Liangshan spirit blazes anew. These heroes stranded overseas resolutely lead their forces north, fighting their way back to their homeland. With their passion and loyalty as blades, and their brotherhood as armor, they continue their legend on the battlefield against the Jin.
