Having just wrapped up four seasons of Doogie Howser MD, Neil Patrick Harris appears in this episode as delivery boy Tommy Ramsen. Having been found kneeling at the body of a murdered woman, Tommy claims that he merely witnessed the crime--and that he himself was shot by the killer. The police don't buy this story and place Tommy in custody, but Jessica (Angela Lansbury), a friend of both Tommy and the dead woman, suspects that there's more to the situation than meets the eye. ~ Hal Erickson, Rovi
