The season 12 premiere of NCIS will dive straight into action.

Speaking to TVLine.com, showrunner Gary Glasberg revealed that Leroy Jethro Gibbs (Mark Harmon) and McGee (Sean Murray) may find themselves in some big trouble overseas.

"We've got a really significant season opener that brings Gibbs and McGee to Russia for a really big story. A crisis comes up and we immediately launch with a significant adversary who will pop up throughout the rest of the season," he said.

The adversary will be played by Russian actor Alex Veadov, 52, whose long list of credits includes the TV series Alias and an episode of Everybody Hates Chris.

The new season of NCIS will also bring a new lady into Tony DiNozzo's (Michael Weatherly) life. "It's time for Tony to continue to grow a little bit," Glasberg previously told TVLine.com. "He went through a lot last year emotionally and tried to deal with Ziva's departure as he could."

However, Tony's sadness over Ziva (Cote de Pablo) will soon be gone since Glasberg said that it's about time for the NCIS favorite to move on to a new woman. And, Tony will meet this new love interest through a case. "We'll be mature about it and handle it properly, and Michael's excited about it," Glasberg added.

Season 12 of the CBS show will premiere at 8/7c on Tuesday, Sept. 23. The new spin-off, NCIS: New Orleans, will kick off right after.
