One afternoon, while Julie is trying to study for a calculus test, she finds a 1920s flapper ghost named Dottie trying to use her air fryer to "crisp up" some phantom pearls.

They rock the house, but as the final note fades, Dottie the flapper appears on stage, accidentally live-streaming the whole thing to Julie’s Instagram. The secret is out: Julie doesn't just have a band; she has a haunting.

The problem? The band’s instruments are currently being "borrowed" by a group of ghost greasers who think the drums are modern art.
