Catiel GrayField comes from a fairly rich family, but the secret behind their wealth is rather stomach turning. His father, Crowley, captures and sells hunters and monsters. They pin them in a large cage and let them hunt each other down, for fun. If that's not bad, they have people buying turns to go in there and hunt the hunter. Castiel has been there for the past two years of his father doing this, his best friend, who happens to be a vampire, named Benny tries to help. When a hunter-or demon- named Dean Winchester is dragged into the picture Cas might change his mind in leaving. Unless Dean can come. Problem is Dean is the best contestant, and his little brother is trying to save his ass.
