"When a web celebrity is murdered, Castle and Beckett [Stana Katic] explore the flashy world of internet fame," the press release reads.

Guest stars for the episode include Maya Stojan as Tory Ellis, Emily Davenport as Abby Smith, Matt Pascua as Carlos Villegas and James Huang as Edward Han, according to the press release.

The episode is set to air Monday, Oct. 27 on ABC.

Meanwhile, fans are eagerly anticipating the marriage of Castle and Beckett. David Amann, who has stepped into the showrunner role for this season of Castle, told TVGuide.com recently that a wedding is still "possible" this season.

He said that the case of Castle getting into the fiery car wreck and all of the drama surrounding that storyline will eventually be overcome.

"I don't think anybody could be expected to just pick up where they left off," Amann said. "Having said that, the Beckett-Castle relationship has faced a lot of challenges, and this is one that they will overcome."

Castle airs Mondays at 10 p.m. ET/PT on ABC.
