<P> In Jerusalem, Gerry meets Mossad chief Jurgen Warmbrunn, who explains that months earlier, the Mossad had intercepted an Indian military message claiming that Indian troops were fighting the rakshasa, or "dead spirits". Israel had thereupon quarantined Jerusalem, erecting huge walls around it . Just as Jurgen shows Gerry that Israel is allowing survivors to take refuge in the city, loud celebratory singing from refugees prompts zombies to scale the walls and attack . Jurgen orders some Israeli soldiers to escort Gerry back to his plane . On the way, Gerry notices zombies ignoring an emaciated boy . Soon after, one of Gerry's escorts, a soldier who identifies herself only as "Segen", is bitten in the hand, which Gerry quickly amputates to stop her turning . Gerry and Segen escape on a commercial airliner as Jerusalem is overrun, and Israel seeks to protect its remaining borders . </P> <P> Gerry contacts Thierry, and the airliner is diverted to a World Health Organization (WHO) facility outside Cardiff, Wales . When a stowaway zombie attacks in mid-air, Gerry uses a grenade to blow the infected out of the aircraft, but this also causes them to crash . Gerry is injured, but both he and Segen survive . They proceed to the WHO facility, where Gerry loses consciousness . He awakens three days later and explains to the remaining WHO staff a theory he has, based on the people he has seen the zombies ignore: the infected do not bite the seriously injured or terminally ill, since they would be unsuitable hosts for viral reproduction . He suggests that they test this by deliberately infecting somebody with a pathogen from the facility, but the pathogens are stored in a wing already overrun by zombies . Gerry, Segen and the lead WHO doctor go to get a pathogen . As they fight their way through, they are separated; Gerry continues to the pathogen vault while Segen and the doctor return to the main building . A zombie corners Gerry inside the vault, prompting him to inject himself with an unknown pathogen and open the vault, thereby testing his theory . The zombie ignores him, as do those he encounters while returning to the main building . Everybody rejoices at Gerry's success . </P> <P> Gerry and his family are reunited in a safe zone at Freeport, Nova Scotia . A "vaccine", derived from deadly pathogens, is developed and issued to survivors battling the infected, acting as a kind of camouflage . The vaccine also helps survivors to reach quarantine zones . Human offensives begin against the zombies, and hope is restored . "This isn't the end," Gerry comments, "Not even close . Our war has just begun ." </P> <Ul> <Li> Brad Pitt as Gerry Lane, a former United Nations investigator with experience investigating in dangerous war zones . </Li> <Li> Mireille Enos as Karin Lane, Gerry's wife . </Li> <Li> Daniella Kertesz as "Segen" an Israeli soldier who accompanies Gerry during their escape from Israel . </Li> <Li> James Badge Dale as Captain Speke, a soldier stationed at Camp Humphreys in South Korea . </Li> <Li> Ludi Boeken as Jurgen Warmbrunn, the Director of Mossad; responsible for preparing Israel's pre-emptive defenses . </Li> <Li> Matthew Fox as a U.S. Air Force Pararescueman sent by Umutoni to rescue the Lanes in Newark . </Li> <Li> Fana Mokoena as Thierry Umutoni, the U.N.
