doctor. Ofelia tells Daniel they should flee with Travis, but Daniel insists his family can survive alone and will join his cousin later. The next morning, as the Clarks and Manawas start driving away, the National Guard arrives and quarantines the block. While Travis says, "It's going to get better," Daniel laments that it’s, "too late," as he watches a guardsman mark the neighboring house. Days after the National Guard quarantines the neighborhood into a Safe Zone, residents try to live normally. Tensions build under the military rule. Ofelia kisses Adams, who was unable to get Griselda's medicine. She sneaks outside the fence to investigate and finds evidence that the guardsmen killed civilians, even the uninfected. Daniel warns Madison of his El Salvador experience, when the sick were taken under the guise of receiving hospitalization but instead killed. Soldiers take Griselda and Nick to a hospital, but Nick's family protests his departure. Liza agrees to go to assist the medical team, despite not wanting to leave her son. Travis retreats to the roof and sees the signal from the Dead Zone. Seconds later, he sees and hears gunfire, followed by darkness. Madison discovers Daniel detaining Adams in the Trans' basement. Travis learns that Daniel tortured Adams into revealing what "Cobalt" means: in the morning, all civilians will be killed, and the guardsmen will evacuate the city. Griselda dies of septic shock at the hospital; Liza shoots her brain to prevent reanimation. Daniel visits a nearby sports arena to verify Adams' story that it was sealed with 2,000 now-zombified civilians inside. The group drives to the National Guard's headquarters to rescue Liza, Griselda, and Nick. Adams agrees to be their guide when let go by Travis. The group infiltrates the base after Daniel distracts the guards by leading a horde of walkers from the arena. Travis, Madison, Daniel, and Ofelia go inside, while Alicia and Chris stay behind. Meanwhile, the walkers breach the perimeter defenses and swarm the base. Travis' group reach the holding cells and set the detainees free before reuniting with Nick, Liza, and Strand. They try to escape through the medical ward, where they discover Dr. Exner has euthanized all of the patients. Dr. Exner tells them of an escape route before presumably committing suicide. Before they can escape, the group encounters Adams, who shoots Ofelia in the arm. Enraged, Travis brutally beats Adams and leaves him for
