Buddha Assassinator aka Shogun Massacre is a 1979 martial arts film directed by Chin Woo Tung, starring Korean kicker Hwang Jang Lee.

Plot

Prince Tsoi (Hwang Jang Lee) is the cruel lord of the Ching regime. He has earned his high rank by using his Lohan Fist techniques to destroy the Ming rebels, who, in turn have targeted Prince Tsoi for assassination. Enter Shao Hai (Meng Hoi), a naive kung fu scholar who earns a living by acting as a janitor for the local Shaolin Temple. The monks here apparently don't take their positions too seriously, as they spend their days bullying Shao Hai instead of praying or practicing the martial arts. Shao Hai lives with his Aunt who adopted him, and learns the martial arts from his drunken master Uncle (Chien Yuet San, doing his best Sam the Seed routine), formerly a head monk of the local temple. The day Prince Tsoi comes to the temple, Shao Hai watches the arrival from the roofs above. He sees incognito rebel assassins about to attack Prince Tsoi, and yells out to the Prince to take cover. Upon hearing Shao Hoi's warning, the guards leap into action and chase off the rebel offenders. Prince Tsoi then shows his gratitude towards Shao Hai for potentially saving his life.

Prince Tsoi (who really doesn't like Shao Hai) allows the young man to think he has gained favor with the Ching. So this immediately goes to the head of Shao Hai and he goes around alienating those around him. Meanwhile, Shao Hai's Uncle asks him to spy on Prince Tsoi to determine which form of martial arts he practices. When Shao Hai informs his Uncle that the Prince practices Lohan style, he convinces Shao Hai to ask Prince Tsoi to teach him this super secret form of kung fu. The Prince is suspicious of Shao Hai's desire to learn Lohan Fist, but agrees because he sees the kid as a pawn of the rebels. In short time, Shao Hai learns Lohan and Buddhist Fist techniques. He finally gets to apply these skills when masked rebel assassins penetrate the palace security to kill the Prince. He beats off the assassins, and manages to kill one. When he removes the mask of the dead rebel, Shao Hai goes into shock when the assassin is none other than his Aunt who adopted him. Shao Hai now realizes that he is on the wrong side of this conflict. He goes to seek the advice of his Uncle, who recruits him into the rebellion, something that his Aunt firmly believed in.

The Prince's advisors warn him that someday Shao Hai could become a potentially great opponent with Lohan Fist training. But the Prince still plans to use Shao Hai to expose the underground. Over time, Shao Hai becomes more knowledgeable with the Lohan techniques, and begins to train his Uncle. The Prince finally catches on about whom Shao Hai is, and demands he send his Uncle to the palace to face him. After the two fight to a standstill, the Prince's guards interrupt the fight, giving the Uncle the opportunity to escape. The angered Prince Tsoi organizes a search party to track down and kill Shao Hai and his Uncle. Meanwhile, both men have hidden themselves in the forest where Uncle begins training his nephew in the ways of the Buddhist's Palm; the only known method of counteracting the Lohan Fist. After undergoing training of the Five Elements Buddha's Palm techniques, the enlightened Shao Hai returns to the palace to challenge his opponent. He fights through Prince Tsoi's bodyguards to finally engage the Prince himself. Shao Hai must defeat the Prince not only to avenge his aunt's death, but in the name of freedom itself...
