A lot of people think that Humboldt County in northern California is an American paradise. Small towns in the county like Arcata look like they've been plucked right out of a Norman Rockwell painting.

Mark Chapman and the Humboldt County Drug Task Force are determined to take back the town, house by house. Our cameras follow as they make busts and fly over forestlands searching for hidden marijuana groves.
