When a group of indie filmmakers are ripped off by a crooked distributor, they set out on a mission of revenge, but quickly find themselves facing off against literal bloodsuckers in what becomes the ultimate battle of good vs evil.

The story centers on Billy, an effeminate fan of vintage science fiction action thrillers. His only friend is Cameron, a nerdy film buff who tries to boost his confidence whenever he can. After seeing a UFO land, Billy retreats into his head, imagining that aliens are taking over the town. Cameron is skeptical, as is the rest of the town. Meanwhile, people are starting to die. First, the reclusive cat lady, Percis, is discovered mutilated by Lester, the churchgoing husband of Carolyn, Percis's depressed caretaker. Random deaths soon follow, first a jogger, and then a janitor at the Carbonics Warehouse. A pair of news reporters share this information with the public while the Detective and his Chief try to solve the killings.
