Cas exterminates, or kills, ghosts. He's pretty good at it too. His dad did it before him, until he was killed by one. Now it's Cas' turn, and he and his mother travel across the country, following leads.
They head to Thunder Bay, Ontario, to confront and put down a ghost most locals know as 'Anna Dressed in Blood'. Cas isn't sure what to expect, but he goes in, just to scope it out. Actually, two local teens knock him out and push him inside, trying to scare him even though they don't believe the story.
That is, they don't believe it until Anna appears and rips one of them in half. Cas isn't sure what to expect, especially since the next time he sees her, she beats him up. She's a ghost with extra super powers and for once in his life, Cas doesn't know what to do.
Gruesome and scary. The ending is definitely a twist. It's very enjoyable, despite a couple flaws. And spooky too!
