Featuring riotous tunes, crass humor and sight gags galore, this hilarious genre bender set in 1873 chronicles the tale of Alferd Packer (Trey Parker of "South Park" fame) -- the only American ever found guilty of cannibalism. With Packer at the helm, a party of gold prospectors gets stranded in the midst of a savage Rocky Mountain winter, and next thing you know, ribs and liver are on the menu. "South Park" co-creator Matt Stone also stars.
