“I think you feel trapped and you’re serious as hell! But right now, I need you to think about the people who love you. And they need you to PUT DOWN THAT GUN!!”
These are the stirring words of Detective Nikki Heat. Okay, they’re actually the audition script words of Natalie Rhodes (guest star Laura Prepon), the beautiful actress who will be playing Nikki in the movie. And, according to Castle, the words aren’t all that stirring. That’s probably because the screenwriter made lots of changes while adapting his novel. Castle’s not all that thrilled with Natalie Rhodes either. He doesn’t think a woman who was a braless coed in a movie called “Knife 2” should be playing Kate Beckett…er…uh…Nikki Heat.
Fortunately, there’s nothing like a murder to take your mind off casting woes. High-end matchmaker Stacy Collins is found skewered by a fence in an alley. Hours earlier, she was at a surprise party thrown by all the happy couples she’d united. Ryan wonders who would want to kill someone who gave couples such joy. That’s probably because he’s about to propose to his girlfriend. He just isn’t sure how to pop the question.
Castle is shocked when Nikki Heat shows up at the crime scene. Yes, the famed actress Natalie Rhodes has been granted permission to shadow Beckett. She wants to get to know the real Detective Heat. As Natalie researches her role, the team learns that the victim’s ex, Brad Williams, argued with her before she was killed. Natalie is impressed with Beckett’s interrogation tactics while questioning Brad. She’s less impressed with Castle, who is horrified to hear that she never even read his book.
