Dean and Sam investigate the case of Olivia Jenkins, a talented Show jumper who died in a tragic car accident. Is it her ghost haunting the highway she died on or is it something darker?

Olivia has spent the past seven years as a hunter after being cast out by her own family. Trusting people is a big issue for her, and one of the only people that she does trust - Bobby - decides to make her go on a hunt with the Winchesters. Although she's reluctant, she gives in. It's not long before she's comfortable around both boys, and she might even be falling for Sam.

There's an ancient myth that reveals to all those that have read or heard it before of a guardian-a guardian for the angels. The angels have been left to watch after themselves along with facing the consequences of the serious decisions they were forced to make. Olivia wakes up unexpectedly to find herself in the Supernatural world, and she plays a bigger role than she believes.
