Unlike the original series, "NCIS: Los Angeles" will not pick up a ghostly storyline. Instead, the episode called "Killshot" follows the investigation of a United States citizen of North Korean descent murder. The secrets to classified software are thought to be lost until NCIS uncovers a suspect from Director Vance's past. Through the promo, it is revealed that Pauley Perrette aka Abby in "NCIS" will make a cameo.
The crossover had been revealed even before the shows began their new seasons. Executive Producer Shane Brennan said in July that Abby will have a "fun little cameo" in the spin-off to help the Los Angeles team to solve a case.
"Killshot" air on Tuesday, October 20 at 9/8c.
