Since losing his eyesight in an accident, Man Sun-Hop has been continually harassed and despised. But instead, his determination and perseverance are so reinforced that he has qualified as a barrister. He has also developed an acute sense beyond sight which helps him to gain the status of Blind Legal Knight in the legal profession. However, nobody really knows his true character. Fortunately, Kuk Yat-Ha, his flatmate and private detective, and Chiu Ching-Mui, a legal executive with mob connections, are two buddies he can always rely on. The trio is known as the Three Sword Fighters who defy the powerful and are always ready to seek justice for the underprivileged.
