Unforgiven

In 1881 in Big Whiskey, Wyoming, two cowboys, Quick Mike and "Davey-Boy" Bunting, attack and disfigure prostitute Delilah Fitzgerald with a knife after she laughs at Quick Mike's small penis. As punishment, local sheriff "Little Bill" Daggett orders the cowboys to pay compensation in the form of several horses to the brothel owner, Skinny Dubois. The rest of the prostitutes are outraged by the sheriff's decision and offer a $1,000 reward to anyone who kills the cowboys. This infuriates Little Bill when he hears of it, and furthers his resolve to enforce the law that does not allow guns in town. Read more on Wikipedia.
