In a world devastated by the infected, Francis and Bill are all that's left of their group. Zoey and Louis are gone, leaving behind an emptiness that both men struggle to cope with. As they push forward through the ruins of what used to be, Francis and Bill find themselves relying on each other in ways they never imagined. The tough biker and the war-hardened vet are more alike than they once thought, but their grief and survival instincts often clash. Together, they must find a way to keep going, not just to fight the infected, but to face the loneliness and loss that comes with being the last two standing.
