故事围绕着Shawn洞察秋毫的能力而随之展开。
After a series of 'accidents' he rightly assumes to constitute attempts at his life, merciless TV talent show 'American Duos' key judge Nigel St. Nigel refuses to lets security compromise the production, which happens to be in Santa Barbara this week, so he hires Shawn as psychic watchdog, going undercover as contestant with Gus. Near-fatal incidents continue, so obnoxious prima donna Nigel gets to stay at highly unamused Henry's home. Shawn and the police meanwhile check out disgruntled failed contestants, the producer Lester Beacon and both fellow judges.
