Heller tells Jack that he has agreed to surrender to Margot at Wembley Stadium. Jack argues that they still have time to stop her, but Heller reveals his Alzheimer's diagnosis and insists on proceeding. Mark helps organise the covert departure while Heller says goodbye to Audrey without explaining his plan. Jack removes the president's implanted tracker and escorts him past the security detail, then flies him to the stadium before the deadline.
Kate pushes the CIA's doctors to wake Simone despite the danger to her condition. Simone supplies Margot's former address and says Naveed hid evidence beneath the floorboards. Agents recover a disk and pass its contents to Chloe, who searches for a way to interrupt the drones. Margot and Ian have already abandoned the hideout. Ian objects to his mother's promise to destroy the drones after Heller's surrender, but she intends to honour the agreement if the president appears as required.
Jordan calls Navarro for assistance, giving the station chief another chance to send the assassin after him. Suspecting the setup, Jordan confronts the gunman. Their struggle leaves Jordan stabbed and the assassin shot, while Kate becomes concerned about her missing colleague. Audrey discovers that Mark helped her father leave and lashes out at him. At Wembley, Heller tells Jack that he has arranged a pardon for him, then walks onto the pitch. Margot watches the drone feed and launches a missile. The stadium erupts in an explosion, leaving Heller apparently killed.
