Sam (Jared Padalecki) and Dean (Jensen Ackles) listen to a message on John's (Jeffrey Dean Morgan) cell phone from a woman named Ellen (guest star Samantha Ferris) and decide to track her down.

They are shocked to discover Ellen runs a road house that also serves as a gathering place for hunters like themselves. Meanwhile, at a small town carnival, a clown is persuading children to let them into their home so he can murder their parents.
