NCIS is still going from strength to strength each week despite the recent loss of team leader Leroy Gibbs (played by Mark Harmon) and other major characters in recent years. With new boss Alden Parker (Gary Cole) heading up the team, the 20th season of the action-packed CBS series has just added an Emmy-winning guest star to its repertoire.

It's also unclear when exactly the episode will air, though it could be released as soon as this month.
