NCIS Los Angeles is set to air its penultimate episode of season 14 before concluding the show's 14-season run. Fans can expect major danger ahead for Kensi Blye and Marty Deeks as they go undercover to hunt down criminals who have stolen military-grade weapons. The crime-busting couple meets with Admiral Hollace Kilbride, who introduces them to AFT Agent Newsome. The Admiral warns the agents that they do not have much background on the situation, except for the ten bodies tied to the target. He tells Agent Newsome to signal Kensi and Deeks if he believes his cover has been compromised and urges him to avoid any cowboy stuff to prevent a dead ATF agent on his watch.
