Last Man Standing (1996)

With its unpaved streets and rickety buildings, Jericho, Texas is an unlikely outpost for gun-toting mobs from Chicago. But with Prohibition in full swing, tweed-suited rum-runners have corrupted and terrorized this sleepy border town. Civil law is dead. Like their bosses in the Windy City, the leaders of Jericho's rival crime families are warring for control of a lucrative bounty of booze: truckloads of 100-proof, making their way from Mexico to a thirsty nation's illicit network of gin joints and speakeasies. Fatefully, a mysterious loner, Smith, passes through looking for a place to spend the night, but quickly decides to cash in on the action. He cleverly hires himself out to each gang while remaining loyal to no one but himself. A soldier-of-fortune with his own agenda, he betrays both sides to the other in a bold attempt to destroy the bootleggers and rescue what remains of Jericho's shell-shocked residents. But a traitor cannot live among mercenaries without being exposed and killed.
