"Model Behavior" -- Gibbs and the team investigate the murder of a supermodel filming a reality TV show on a Marine base, on NCIS, Tuesday, Dec. 13 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Stephen Cragg directed the episode from a script by David J. North.

At the start of the investigation, the team believes the model may have committed suicide, but they uncover a twisted love triangle involving the Marine staff sergeant working on "Boot Camp Babes," a drug addicted ex-boyfriend and a disgruntled adoptive father, who is also the executive producer of the reality show. Meanwhile, Director Shepard is annoyed when Gibbs doesn't show up at an awards ceremony where he is being honored.
