When the latest season of the pair-based singing competition show American Duos prepares for an audition show in Santa Barbara, the cruel British judge Nigel St. Nigel (Tim Curry) finds himself in a panic after a series of near-miss attempts on his life and hires Santa Barbara's most reliable psychic detective to protect him.

Nigel believes that the police are in on the conspiracy, so Shawn and Gus go undercover as contestants on American Duos to protect him.
