Summary of the story:

• This series is a political story on who would gain control of the Tang throne. Felix Wong plays Kong Fung, a man who is obsessed with learning kungfu and becoming the best in martial arts is his only goal in life. Miu Kiu Wai plays the 2nd prince (Lee Sai Mun) of the Tang dynasty who wants to become the emperor of the Tang dynasty. Tong Chun Yip plays the 3rd prince (Lee Wai Gut) of the Tang who also wants to become the emperor of the Tang dynasty. Finally, Yung Mei Ling plays Kong Fung's girlfriend in the beginning, however Kong Fung dumps her so she becomes Lee Sai Mun's girlfriend later.
The story is also kind of sad so if you don't like sad stories then don't see it.

• Acting:
It features an all-star cast and they performed that way. Yung Mei Ling played kind of a sad role as Chun Sik Sik. It's quite different from the Wong Yung role in Legend of the Condor Heroes '82. Felix Wong played Kong Fung well. He brought out the emotions of Kong Fung and made the audience feel what Kong Fung was going through. Miu Kiu Wai was noble and cunning as the 2nd prince, and Tong Chun Yip did a good job in his usual prince role.

• Fighting Choreography:
There were some really good fight scenes in this serial. However, with the limited technology during that TVB had in 1983 the moves looked kind of slow. The little special effects they did employ looked pretty cheesy and messed up compared to today's standards. Also, the places which they fought looked faked at times which is typical TVB. I also want to point out that this series does not focus on martial arts as some of the other series that you may have seen with Felix Wong in it. There are a lot of fights, however, it's not so much the story about who will gain the top spot in the martial arts world. The series really revolves around politics.

"決戰玄武門"是一部宮闈武俠劇，講述唐朝武德年間，李淵的三個兒子李建成、李世民、李元吉爭奪世子一位，而勾心鬥角，互相殘殺的故事。

唐高祖李淵(張英才)有三子一女，長子建成(歐陽震華)庸碌懦弱；次子世民(苗僑偉)精明能幹，最為李淵寵幸；三子元吉(湯鎮業)魯莽好鬥，最具野心；三兄弟均想繼承皇位。世民助父開國，居功至偉，視帝位為囊中物，於是微服出遊，為日後登基鋪路。

為了招兵買馬，世民以平民身份加入武林大派昊天門，結識天下英雄。少年江豐(黃日華)自幼受盡欺凌，矢志成為天下武林至尊，後得世民欽點，加入昊天門。為了潛心學武，江豐黯然與愛侶秦惜惜(翁美玲)分手，惜惜傷心投河，為世民所救，兩人互生情愫。

後來建成被冊封為儲君，並與元吉結盟，世民深感形勢不利，急謀對策，終邀得江豐相助。遊俠孟青平(惠天��)行刺李淵失敗，李淵得悉行刺之事與建成、元吉有關，遂召他們入宮查問；世民趁機伏兵玄武門，將建成、元吉殺死，引發轟動天下的「玄武門之變」﹗
