White hat: Seth Bullock (Timothy Olyphant), left, is a morally challenged adulterer and Montana marshal who leaves his job to start an honest hardware business in the gold-mining camp of Deadwood, S.D. He also becomes the camp's sheriff. In Deadwood, he finds a rough bunch of gun-slinging swindlers and gold-crazed miners each one hungrier and meaner than the next. Sheriff Bullock does his best to uphold the law even when a slimy Al Swearengen (Ian McShane), right, challenges his honor and efficacy as a lawman. Black hat: Al Swearengen as played by Ian McShane is a quintessential black hat completed by his ominous black mustache. The incipient Swearengen runs the local brothel and bribes politicians with money, reciprocity and intimidation. Swearengen's shady deal making doesn't end there, he's eying Bullock and wants him out of town and out of business.
