Following an explosion at a fish market, the NCIS: LA team partners with an undercover DEA agent to determine if the incident is an act of terrorism or a botched drug smuggling deal. Meanwhile, in Afghanistan, Granger and Kensi investigate a helicopter crash that could be tied to their ongoing search for the infamous white ghost.

Eric witnesses his friend, a computer systems expert, being attacked by people who want information that could redirect a missile; Kensi runs into a familiar face in Afghanistan.

After learning that Special Agent Kensi Blye disappeared and the Taliban may be he holding her captive, Hetty sends the NCIS: LA team to Afghanistan on a rescue mission.

When Kensi and Deeks announce to the team they are moving in together, coincidentally, Hetty assigns them to protection detail for Jack, Kensi’s ex-fiancé, who is in possession of a list containing important contacts in Afghanistan that people are willing to kill to get their hands on.
