Y/N thought her life at Stanford was finally on track - until she met Sam Winchester, her old teenage love and the person with whom she shared unforgettable moments. The reunion awakens dormant feelings, but things get even more complicated when a supernatural entity attacks during a Halloween party, forcing the two to join forces on an unexpected hunt.
In the heat of danger, the connection between them rekindles, leading Sam to break up with Jess and give in once and for all to the feeling that never died. However, before they can think about the future, Sam's brother Dean and Y/N's sister Emma appear with urgent news - their parents, John Winchester and Anthony Singer, went hunting together and disappeared without warning. Without leave traces.
Now, Y/N and Sam are forced to abandon their college dreams to follow a dark and dangerous path, facing evil forces, family secrets and intense love, as they fight to save their parents - and, perhaps, themselves.
