Stacy is a teenage girl who resides in Lebanon, Kansas. She forms a relationship with newest girl in town, Max.
On "Skip Day", Stacy and her friends have ditched school and are hanging outside the Lebanon movie theater discussing the rumors about the "Campbell brothers" and "their weird sidekick with the trench coat. And what about that kid with the dumb Bambi look on his face all the time." Max has a crush on Stacy, and in order to impress her she steals the Impala - complete with the collection of cursed and mystical objects Sam and Dean are taking back to the bunker.
The kids go to a house out on Route 36, and go through the items they found in the Impala. From an old cigar box, the ghost of John Wayne Gacy emerges and terrorizes a a teen boy named Ethan, attacking him in the bathroom, which sends Ethan quickly running out the house. When a girl, Bea, chases after Ethan, she alerts Sam and Dean as to what happened. When Sam and Dean go inside the house, Sam quickly notices Gacy's cigar box and gets to work trying to burn it. Just as Gacy manifests before Dean, Sam is able to set the box aflame as Eliot, Max, and Stacy rush into the house to witness Gacy's spirit burn away. Sam and Dean explain to the kids that monsters and ghosts are real, but they cannot tell anyone.
After use of the Baozhu causes John Winchester to appear from 2003, the timeline is disrupted. Max passes Sam on Main Street and doesn't recognize him. She and Mac and Elliot are eating at the restaurant where her mother Caitlin works, when Zachariah and Castiel appear from 2003 to find out who is meddling with the timeline. Sam and Dean arrive, allowing Caitlin and the kids to escape.
After the timeline is restored, the kids are discussing that the Winchesters are hunters, as Max and Stacy walk hand in hand.
