In order to locate Arkady in Russia, the NCIS team goes undercover with his daughter, Anna, at a gala in Los Angeles to gain access to the Russian Consul General’s computer.

While they’re in Russia, Callen, Sam and Anna craft a plan to break Anna’s father and his CIA agent companion out of prison. Also, Special Agent G. Callen finally learns what the “G” in his name stands for, and in Los Angeles, Kensi and Deeks take Eric into the field on an assignment.

Hetty goes rogue, leaving the NCIS team completely in the dark, and the mole kidnaps one of the agents.
