In 1864, mercenary Clyde McKay leads a squad of daredevils tasked with a dangerous mission by Captain Lynch of the Confederate high command: to infiltrate and raid a Unionist army fortress where a million dollars in gold is stowed away in boxes of dynamite. A single Colt bullet could send the whole treasure sky high but for these scoundrels - Deker the dynamite specialist, Hoagy the killer, Blade the knife expert, the murderous Kid and Bogard with his brute strength - nothing is impossible. Only madmen could pull off such a job, piercing the enemy lines at the only part of the river that can be crossed and creating a diversion for the garrison at the foot of the mountain where the arsenal is situated. However before long the double crosses begin in this bloodthirsty Civil War tale of revenge.
