Stanley is a 17 year old living under strict parole conditions after being sent to juvenile hall multiple times. He has to live with his grandfather, who is extremely abusive, in a town that despises him because both of his parents are dead and he is poor. One day, he discovers a vampire living in his shed that will eat any living thing that crosses the threshold. Stanley is terrified, but his best friend Dommer thinks they should use the creature to get rid of all the bullies and tormenters in their lives.
