NCIS returns Tuesday February 7 for a watershed event in show history.

It is, after all, the 200th episode of the CBS procedural, now in its ninth season and the #1 drama on TV. For Leroy Jethro Gibbs (star and executive producer Mark Harmon) it's a time to look back upon his life.

During a routine stop for his morning coffee at his favorite diner, Gibbs unexpectedly finds himself staring down the barrel of a gun, forcing him to question choices he has made in the past and present.

The 200th installment also serves as a "here's to our fans" moment of sorts, with a number of familiar faces returning in the alternate reality to which Gibbs' mind drifts (a la the 1998 movie, Sliding Doors).

Muse Watson (Mike Franks), Ralph Waite (Jackson Gibbs), Joe Spano (Senior FBI Agent T.C. Fornell), Darby Stanchfield (Shannon Gibbs) and Rudolf Martin (Ari Haswari) appearing in the milestone episode.
