While Gus tunes in to a television favorite, a singing competition called American Duos, Shawn would rather tune it out. He is more than happy to have their viewing experience interrupted by a phone call from Juliet, asking them to come to the police station. Much to his dismay, Shawn realizes that he didn't escape the show after all. One of the judges from the program, the crass Nigel St. Nigel, is in need of Shawn's help. He has been the victim of numerous life-threatening attacks and needs protection. While Lassiter interviews all the potential suspects, Shawn and Gus must go undercover—as contestants on American Duos.
