Marg Helgenberger is moving back to the military.

The CSI and China Beach vet has joined Fox's Behind Enemy Lines reboot pilot, The Hollywood Reporter has learned.

Loosely based on the 2001 movie of the same name, the pilot is described as a military soap thriller wherein a group of U.S. soldiers find themselves trapped behind enemy lines. The drama's multi-perspective narrative closely follows the soldiers on the ground, and the officers and service men and women on a nearby aircraft carrier, along with intelligence officers in Washington as they attempt to bring our heroes home safely and under the radar.

The Emmy-winning actress will play Navy Admiral Bobbie Decker, the most powerful woman in the military. Fierce but fair, Bobbie is a straight shooter who will do anything to keep her men and women safe.  

Nikki Toscano (24: Legacy, Shades of Blue) penned the pilot, which McG (Charlie's Angels) will direct. The two will executive produce with Marty Bowen, Temple Hill's Wyck Godfrey (who produced the feature), The Blacklist's John Davis and John Fox via Davis Entertainment, with Albert Page set as a co-executive producer. Davis also produced the original movie for 20th Century Fox. 

The film Behind Enemy Lines, starring Owen Wilson and Gene Hackman, grossed $92 million worldwide and led to three direct-to-video sequels.

The new TV role brings Helgenberger into the Fox fold after more than 15 years at CBS. Best known for her 12-season stint on CSI, her recent roles have included Intelligence and the third and final season of Under the Dome, as well as the CSI wrap-up TV movie. She is repped by ICM, Sanders Armstrong Caserta and attorney Fred Toczek.
