Sarah and Casey follow a trail to Russia as they investigate the mysterious Volkoff Industries and its operative, Marco (Dolph Lundgren).

After traveling the world, they find an empty safe in Mary’s Los Angeles hideout, but a Chinese restaurant menu offers a clue.

Struggling to find a job, Chuck is repeatedly sabotaged by General Beckman, who eventually forcibly reinstates him and Morgan into the CIA.

At the Buy More, now a CIA/NSA base, Chuck flashes on an EMP device connected to Volkoff Industries, matching the restaurant logo on the menu.

Back in Burbank, Chuck plans to tell his sister Ellie about rejoining the CIA, but she surprises him with news of her pregnancy, causing him to withhold his secrets for now.
