Determined stoners Chaz Markis and Hayden Couter set out to find Devil's Root, a little-known and perhaps mythical hallucinogen that may or may not exist. Supposedly, it only grows in Japan's Aokigahara Forest, the infamous Suicide Forest, and is somehow responsible for the rash of suicides and odd occurrences that have happened there. As they venture deeper into the woods and farther from civilization, they soon discover that maybe all the other drugs they have a past with are much safer and far less powerful.
