ABC’s “Designated Survivor” is slowly showing President Tom Kirkman, a former Secretary of Housing and Urban Development, settling in to the White House. Episode 3 saw Kirkman realize the Republican’s designated survivor Congresswoman Kimble Hookstraten’s true intentions. Also, Aaron Shore got promoted to Chief of Staff while Emily Rhodes became his Special Advisor.

Episode 4 of “Designated Survivor” is going to show President Kirkman (Kiefer Sutherland) learn who the real enemy is behind the attack on the Capitol that wiped out almost all cabinet members. The official synopsis of “The Enemy” states that Kirkman will have to deal with the prospect of war.

However, Tom Kirkman has more than just a brewing war to deal with in the upcoming episode of the ABC series. After confessing to the public in an interview that he was fired by the now deceased President Richmond hours before becoming the designated survivor, he is faced with domestic troubles. A mutiny erupts with several people protesting his accession to Presidency.

Kirkman orders Emily (Italia Ricci) to monitor the situation at the White House and Washington, D.C. while he commands the federalization of Michigan national guards. In particular, General Cochrane (Kevin McNally) is sick of his leader’s diplomatic attitude. He wants to attack the enemy and he wants to do it now.

 “Designated Survivor” Season 1, episode 4 will also see Kirkman’s wife Alex (Natascha McElhone) go to Hookstraten (Virginia Madsen) for help. It’s safe to assume that she will not inform her husband before seeking her out. However, the encounter will not be pleasant for her.

The promo of episode 4 also shows Aaron (Adan Canto) explaining Emily that her boss is now going to do things that she won’t agree with. After all, he is the most powerful man in the world.

“Designated Survivor” Season 1, episode 4 premieres on Wednesday, Oct. 12 at 10 p.m. EDT on ABC.
