Love Potion #666

Leanna, a sociopathic sexpot fresh out of prison, and Mikey, her meathead boyfriend, steal her mother Teena's experimental sex drug, arm themselves to the teeth, and hit the road intent on selling it to a powerful narcotics kingpin on the other side of the country. When Teena, a voodoo priestess-in-training, returns home from Haiti to find her house ransacked and her love dust gone, she devises a terrifying plan to pursue the young lovers to the bitter, bloody end.
