With their town under siege and all evacuation routes blocked, Sheriff Primrose is quickly running out of options. Falling back on his military training, he enlists the help of first-responders and retired officers, forming an armed posse. Their goal: round up as many survivors as possible before night falls, and then barricade themselves somewhere safe until dawn.
Beginning where Ashes to Ashes left off, All Fall Down amps up the action level to eleven in a cataclysmic fight for survival.
