The final season finds Carrie Mathison recovering from months of brutal confinement in a Russian gulag. Her body is healing, but her memory remains fractured – which is a problem for Saul, now National Security Advisor to the newly ascendant President Warner. The top priority of Warner's young administration is an end to the "forever war" in Afghanistan, and Saul has been dispatched to engage the Taliban in peace negotiations. But Kabul teems with warlords and mercenaries, zealots and spies – and Saul needs the relationships and expertise that only his protégé can provide. Against medical advice, Saul asks Carrie to walk with him into the lion's den – one last time.
