"We're all guilty of something, aren't we?"

Amy is in big trouble with the Law. A late-night phone call from a stranger implicates the 16-year-old in a terrorist plot. But when the nefarious man suddenly vanishes, Amy becomes the FBI's prime suspect. To prove her innocence, she embarks on a fantastic journey to find her mysterious night caller.

The clues to the mystery man's whereabouts are few, but all point to a dingy, old barbershop that caters to the rich, famous, and powerful. What draws them to the shop's eccentric barber is puzzling, until Amy stumbles upon his dark secret: his discovery of a magic shampoo that alters your personality! 

As Amy investigates the wizard barber, she crosses paths with many of his customers, including a stressed-out pop music idol, a war veteran with PTSD, and others suffering mental challenges. Her quest offers a rare glimpse into the complexity of human behavior, including hers, as she struggles with her own adolescent issues.
