A rogue Division Agent Markov was undercover in Uzbekistan and won the election for President. Division wants to take him out. Birkhoff suggests they create a foolproof mask for Michael to go undercover as Markov when he is in America visiting the US President. After a few weeks in Uzbekistan, they will stage a natural death, so there are no ties to the US. They capture Markov, but they didn't count on him having a fail-safe. This requires them to release Markov. While trying to destroy Markov's recorded message, Birkhoff finds another recording in which Markov explains why he killed the US President. With that knowledge, Division has to take action to capture Markov. They get him before he can attack the President, Michael pretends to be Markov, and then they stage the natural death.
