A gang of bandits take over a passenger train in north Mexico. They threaten to kill everyone on the train unless the bandit commander's brother is released from a US prison. There's just one problem: the brother is due to be hanged for a bloody raid into a boarder town. And that's if the national guard can prevent the citizens from lynching him. Ordered to write a letter outlining the commander's demands, a law student ("We need someone who can think in Spanish and write in English!") addresses the letter to the only two men who can save the day.
The heroes turn out to be Hank Bracket (Rod Taylor) and Johnny Reach (Dennis Cole), two mercenaries who will only take a blank check in way of payment, since anything less isn't worth their time. Can Bracket and Reach come up with a plan to free the passengers before time runs out? Will the railroad president allow them? And what about the mysterious senora who claims to be the wife of the soon-to-be-executed bandit's brother?
Powderkeg can only be described as Fistful of Dollars meets Mission Impossible. The director created an American response to all the cynical EuroWesterns flooding out of Italy and it worked. The soundtrack deserves it's on special release and the acting is superb. Big bonus points to the late Fenando Lamas for creating one of the most memorable villains of the last century.
