Get ready to boldly go where no man has gone before, Castle fans!

In Season 5, Episode 6: "The Finale Frontier," Castle and Beckett find themselves investigating the cast and crew of a popular television series after a dead body is discovered at sci-fi fan convention, à la Comic-Con. But that's not the only homage to Castle's nerdtastic fandom.

Look out for a plethora of Firefly references, complete with a TV character named Captain Max Richards, an obvious fan nod Nathan's reign as Captain Mal Reynolds on the short-lived FOX show. Star Trek lovers will also be pleased to see a cameo from director Jonathan Frakes.

Check out the official synopsis below via ABC:

"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."

Guest stars include 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.

Original Air Date: Castle Season 5, Episode 6: "The Final Frontier" airs on Monday, Nov. 5 at 10 p.m. ET on ABC.
