Major Players: Special Agent-in-Charge Leroy Jethro Gibbs (Mark Harmon), the big boss; Senior Special Agent Tony DiNozzo (Michael Weatherly); quirky forensic specialist Abby Sciuto (Pauley Perrette); Special Agent Tim McGee (Sean Murray); newly-recruited Special Agent Ellie Bishop (Emily Wickersham); medical examiner Ducky Mallard (David McCallum); Director Leon Vance (Rocky Carroll).
Basic Premise: A spin-off of JAG, the No. 1 drama on television follows the team of agents from the Naval Criminal Investigative Service as they solve crimes week after week. They're led by former Marine Gibbs, who's haunted by the murder of his wife and daughter. Season 12 finds resident goofball Tony wading back into the dating pool after former agent Ziva David broke his (and millions of viewers') hearts in Season 11 by opting to quit the team and return to her native Israel.
