In the late 1860s, Idaho City is the largest city in the American Northwest, a bustling mecca for those toiling away in the hot sun, desperate to find the next big strike of gold and a few nightly comforts. The men and women of Idaho City, eager for their own share of that hard-fought golden treasure, do their best to serve the needs of the frontier, but as in any boom town, there are those who wanted to make quick money free from the burden of an honest day's work. This atmosphere draws outlaws, in particular a gang known as the Ghost Riders, a mysterious and dangerous crew of wraithlike figures, draped all in white, on horses that wore the same disguise.
