Carrie has been hospitalized in the wake of the explosion that killed Al Zahrani in the heart of D.C. When Saul comes to retrieve her, he discovers her on a manic flight, postulating a mile a minute about Abu Nazir. Saul finds himself charged with looking after his damaged friend, and by applying his sense of order to Carrie’s chaotic theories, unearths what appears to be the heart of the terrorist mastermind’s plot.

Meanwhile, Brody has taken his family to Gettysburg, to spend one last weekend with them before his congressional campaign begins — and before his fatal mission is to take place.
