Durant informs the Underwoods that a research facility in Antarctica has been taken over by an unidentified military group, suspecting the Russians. Meanwhile, it appears that Aidan has been kidnapped and may be forced to reveal secrets. The Congressional Black Caucus considers supporting Conway instead of Frank, but the meeting goes very poorly. On a plane back to New York, Conway berates the pilot for not giving him the controls and declares maniacally that he will be President. Hammerschmidt discovers that Sean visited Lisa, prompting Hammerschmidt to fire him. He later investigates the death of Zoe Barnes.

Claire, Frank, and Cathy learn it is the Russians who have kidnapped Aidan.
