Weirdsville (2007)

Dexter and Royce, two stoners in the small town of Weedsville, attempt to cover up the overdose of Royce's girlfriend Matilda. What leads from an old drive-in being perfect place to ditch her turns into the accidental discovery of a Satanic cult, who brings Mattie back from the dead after their ritual is botched. Along with the two's dealer Omar on their tail, how will these buddies and their slightly-off lady-on-board deal with the dangers of drug debt and demon-worshipping magic?
