On ABC tonight Castle returns with a whole new episode called “The Final Frontier.” On tonight’s show Castle and Beckett take on a murder at a Sci-Fi Covention. Did you see last week’s premiere episode? We did and we have a full and detailed recap here for you.

On last week’s show while investigating a shocking ritualistic murder, Beckett and her team uncovered surprising evidence linking Castle to the killing. As the evidence against him mounted, loyalties were tested, and when surprising revelations come to light, Beckett began to wonder how well she really knew her new lover and partner of four years.

On tonight’s show when a body is found at a sci-fi convention, Castle and Beckett are warped into the heart of fandom — a world of egotistic celebrities, diehard costumed fans and enough drama for two galaxies. In a Castle “shocker”, Castle bumps into Alexis at the convention and is shocked at her revealing anime outfit, it’s the sexy side of sci-fi.

Guest Cast Tonight: Armin Shimerman as Benjamin Donnelly, Ed Quinn as Gabriel Winters, Christina Moore as Stephanie Frye, Erin Way as Audrey O’Neill, Chris McKenna as Simon Westport.

Tonight’s episode is going to be great and you won’t want to miss it. So be sure to tune in for our live coverage of ABC’s Castle tonight at 10PM EST!
