NCIS star Katrina Law hints the upcoming season 19 finale will be pretty action-packed. The TV landscape is changing at a rapid pace, yet NCIS remains a steady and reliable performer.

NCIS season 19 fielded the show's biggest shakeup yet when longtime leading man Mark Harmon departed after only appearing in 4 episodes.

The former Arrowverse star boarded the series at the end of season 18; her character, Agent Jessica Knight, fell in with the core team after her colleagues in the REACT Unit died while on a mission.

In addition to Law and Cole, NCIS currently stars Sean Murray, Valderrama, Brian Dietzen, Diona Reasonover, Rocky Carroll, and David McCallum.

The NCIS season 19 finale is still well over a month away, yet Law was able to share one intriguing tease about it with TVLine.

Though the actress couldn't offer any story hints, she did suggest the finale (which airs on May 23) will be pretty action-packed because of one major behind the scenes reason.

Regardless of how season 19 wraps up, fans can rest assured that NCIS will be back for another batch of episodes later this year.

This time next year, there could be another major shakeup headed for the NCIS universe; fans will just have to stay tuned for future updates.
