Revenge of the Drunken Master

Nick and Ruben are hoodwinked into a "shootfighter" (no-holds-barred, to the death) martial arts match by the evil Mr. Lee, who has a grudge against world shootfighter champ(and teacher of Nick and Ruben) Shingo.

A former fighter reluctantly returns to the life she abandoned in order to help her sister survive the sadistic world of illegal fighting and the maniac who runs it.

Two brothers compete in the world's deadliest underground fighting tournament, where they must decide whether to play by the rules or to cast their honor aside and team up to bring down the dark syndicate running the tournament.

Fight everyone and trust no one: it's the code of survival practiced by martial-arts master Casey Bowman after his life of domestic bliss is shattered by a savage act of violence. Vowing revenge, the fearless American stealthily tracks the killer from Osaka to Bangkok to Rangoon with the help of a wise and crafty sensei. His only clues: a series of victims whose necks bear the distinctive mark of strangulation by barbed wire. Fighting to avenge as well as to survive, Casey must sharpen his razor-like responses and take his battle skills to the next level, even using deep meditation to fake his own death. His target: the sinister drug lord Goro, who is flooding the streets with deadly meth cooked at his remote jungle factory. To prepare for his ultimate confrontation, Casey must finally become an invisible warrior worthy of the name Ninja. But just when his prey is cornered, an unexpected twist shows Casey that his battle is only beginning: he truly can trust no one.

Three middle aged men polish their martial arts skills to avenge their fallen master.

In this sequel, Scott Wylde, an American kickboxer, must go to Cambodia to rescue his Vietnamese girlfriend from Russian and Vietnamese troops.
