Beckett and Castle tackle an upscale matchmaker's murder case, and they have company: the actress (Laura Prepon) cast as Nikki Heat, who wants a deeper grasp of her character. Her copycat image soon becomes too much for Beckett, but Castle likes it.
Castle and Beckett learn about life-extension science and how far people will go for the fountain of youth when they investigate a possible homicide in which there's no body. Elsewhere, Alexis hears from Stanford University's admissions department.
