Olena Wilder is just your average teenage girl, who does normal teenage things. She knows how to kill a person at least fifty ways in hand to hand combat, she's trained in the lethal use of weapons, she knows multiple types of martial arts, and she's very good at killing people, say rogue vampires or her distant cousins from Russia and the Ukraine.

What happens when you mix Wilders and Winchesters. Dean and Sam discover not all demons are evil when they meet a family under a thousand-year-old curse. Little do both families know the affect this will have on their futures.
