The sister to Sam and Dean Winchester, she has spent her fair time on earth fighting the world of evil along side with them. It isn't until she gets a call from Dean, where he asks her to take a case they can't take. She must leave the war, leave the life she's known for so long, and fall to earth to figure out why Death has taken over the high school of Ashley Waters. Problem is, so does the Blackbourne team. And they're in for a rude awakening.
