In a world devastated by a deadly virus that turns people into ferocious creatures, life seems to have returned to normal after six months of quarantine in London. The military authorities have established strict control to reclaim the city, rescuing the few survivors that remain and promising to restore order. However, what seemed to be a new beginning quickly turns into a nightmare when one of the refugees, Don, cannot resist the temptation to visit his wife, who was believed to be dead during the crisis.
Upon reuniting, old wounds are reopened and chaos erupts. Soon, the virus unexpectedly resurfaces, trapping the group of survivors in a desperate struggle for their lives. As the infected begin to stalk the ruins of the city once again, a group of young individuals seeks refuge, including the brave and resourceful Tammy, who becomes the leader of the group. As the horror intensifies, loyalties are tested, and family bonds begin to crumble.
In this dangerous fight for survival, the characters will have to face not only the lurking monsters but also the betrayal and fear that threaten them from within. With a breakneck pace and moments of intense tension, what seemed to be a second chance soon turns into a race against time to prevent humanity from becoming extinct.
