Plot summary
The president of Russia retaliates for the power system hack by shutting down the oil pipelines to Europe. Henry is convinced that Russia was not behind the hack of Air Force One, but Russell refuses to listen to his concerns or to let him speak to the president. Elizabeth vets the intelligence that supported Russia as the culprit and begins to have doubts herself. After Henry secretly shares his information with Elizabeth, she determines that Ukraine hacked Air Force One and faked an attack on their own plane so that the U.S. would back Ukraine against a Russian invasion.
