The story is all about legendary Colorado cannibal Alferd Packer, played by Trey Parker himself, backed by his crew of Humphrey, played by Stone, and other strange characters in his crew. Very strange Hilarity Ensues. The full movie can be watched for free online at the official site here, as well as the version with the DVD Commentary track.
