Crime procedural "NCIS" is set to return for its 21st season this week, finally giving fans new episodes to sink their teeth into after the cliffhanger that was the season 20 finale.

Fans will be sad to notice one beloved character missing, however, as David McCallum, the Scottish actor who played Donald "Ducky" Mallard, died at the age of 90 in September. But by the looks of it, fans will get an on-screen tribute in one of the upcoming episodes.

Besides paying respect to McCallum, fans have other reasons to look forward to the new season. For one, the first episode appears to continue the storyline of Special Agent Nick Torres (Wilmer Valderrama), who found himself in a predicament at the end of last season.

Here's how to watch the season 21 premiere of "NCIS."
