Armed with the evidence she and Teddy have gathered, Lena asks the White House to authorize the killing of Imad; but the operation is only possible if the CIA works hand-in-hand with Mossad. Imad persuades Iran to provide him access to chemical weapons. The enormous stakes and time pressure lead to a near-rupture between Mossad and the CIA, until Lena extracts more information from the Iranian defector, Imad’s original recruiter back in Beirut, which enables the joint CIA-Mossad operation to enter its decisive, final chapter. Series finale.
