The titular 'Odd Couple' are Sammo (King of Sabres) and Lau Kar Wing (King of Spears). They compete regularly against each other but every encounter results in a draw! Both decide to recruit young pupils and train them up. The late entry of the real villain, the smoldering Laughing Bandit who sports a big scar, has an even bigger grudge against the Kings of Sabres and Spear.
