ABC has released the official synopsis for the April 30th episode of Castle, “Undead Again”.
- When Castle and Beckett investigate the murder of a man with human bite marks on his body, Castle’s wild theories start flying.
- But none are as wild as what their only witness insists happened – a Zombie attack.
- As the evidence pointing towards an undead assailant piles up, the team plunges into New York’s Zombie subculture to find the killer and bring him in — dead, undead or alive.
In other Castle news, a craiglist casting call revealed a few more zombie-lishous details about this upcoming episode. It will apparently center around a grad student named Pete Thompson, whose fiancee Greta had an affair with the murder victim, David Lock. In addition to the action filled zombie scenes, there was also mention of a “Thriller” flash mob scene
