NCIS (Seasons 1–23)

NCIS (2003) is CBS's long-running crime procedural you can watch online on iFILM. A team of special agents handles every case tied to the U.S. Navy and Marine Corps — murders, espionage, stolen submarines, terrorism — regardless of rank. Twenty-three seasons in. Still going.

Timothy McGee (Sean Murray) has come a long way from green rookie. His colleagues Nick Torres (Wilmer Valderrama) and Jessica Knight (Katrina Law) bring field muscle, Jimmy Palmer (Brian Dietzen) handles forensic pathology, and Director Leon Vance (Rocky Carroll) keeps the whole operation from the top floor. Each episode drops a new case; the team closes it before the credits roll.

Produced by Belisarius Productions and CBS Studios, the series launched in September 2003 as a spin-off of JAG and quietly became one of the most durable procedurals in American television history. Five hundred and seven episodes across 23 seasons — and the count is still climbing. Stream every season of NCIS online on iFILM.
