Complete story — includes the ending
Abu Nazir kidnaps Carrie and uses her as leverage to force Brody to give him the serial number for Walden's pacemaker. Brody breaks into Walden's office and provides Nazir the number in exchange for Carrie's freedom. One of Nazir's men uses the number to hack into Walden's pacemaker and induce a lethal heart attack, which occurs as Brody tells Walden he is withdrawing his candidacy for Vice President and rebuffs him as he dies. Saul meets with Dar Adal to discuss Quinn's involvement in Estes' operation, and accuses Estes of plotting to assassinate Brody to mask his own complicity in the drone strike that killed Issa. Estes later has Saul detained in an interrogation room. Carrie returns without backup to the abandoned mill where Nazir held her, believing he is still hiding there.
