On tonight’s Castle season 5, episode 20 “The Fast and the Furriest,” when Castle and Beckett find giant footprints at the site of a vicious murder, the team is forced to confront the unlikely theory that Bigfoot is the killer. But as they trek into the world of primate research, big game hunting and mythological creatures, they realize that finding the man (or beast) responsible may put them on the endangered species list.
The series is based on when mystery-thriller writer Richard Castle (Nathan Fillion), who is called in to help investigate a series of copycat murders based on his books. After completely the job, he finds that he enjoys the experience sufficiently to want to continue it. Pulling strings, he arranges to accompany NYPD Detective Kate Beckett (Stana Katic), claiming he wants to study and use her as a personality basis for his next book series. Once that initial case was solved, Castle and Beckett continued to investigate strange homicides in New York, combining Castle’s writer intuition and Beckett’s creative detective work. Over the past four seasons, Castle and Beckett’s relationship has grown even stronger as they’ve dodged bullets, captured killers, and solved countless murder cases with their unorthodox partnership.
Castle stars Fillion, Katic, Susan Sullivan, Molly Quinn, Penny Johnson Jerald, Tamala Jones, Jon Huertas, and Seamus Dever.
