The Specialists (1969)

Dressed in black, the taciturn friendless gunslinger, Hud Dixon, rides into the dusty town of Blackstone, Nevada. Bent on shedding light on the brutal lynching of his brother, and his alleged involvement in a bank robbery, Dixon crosses paths with El Diablo, his one-armed former friend and Mexican bandit leader. Now, after a chance encounter with the deceased banker's dangerously alluring widow, Virginia Pollicut, Hud is thirsting for revenge, only to find himself in the crosshairs of Sheriff Gideon Ring, the town's businessmen, and a mysterious quartet of hippies. Will Dixon get to the bottom of this violent crime, or will the guns have the final say?
