Get ready to party, Castle fans, because this week’s episode, “Death Gone Crazy,” features college girls who’ve gone a bit wild.

We never thought Castle and Beckett would dive into the adult film industry (unless Castle was dating an ... ahem ... actress), but this week they’re forced to after a high-profile murder.

Check out the official show synopsis for “Death Gone Crazy” via ABC:

“When Beau Randolf, the founder of hit adult video franchise College Girls Gone Crazy, is murdered, Castle and Beckett are confronted with a lengthy list of husbands, fathers and ex-college girls who all have motive. So to find the killer, they must delve deep into the victim's life, where they find surprises at every turn. Also in the episode, Alexis starts a video blog, but Castle is not happy that personal and intimate details about her life are being made public.”

Guest Cast: Kelly Hu as Scarlet Jones, Jordan Belfi as Beau Randolph, Chad Donella as Troy Strickland, Spencer Garrett as Evan Pierce.

Original Air Date: Castle Season 5, Episode 12: "Death Gone Crazy" airs on Jan. 21, 2013 at 10 p.m. ET on ABC.
