Arkansas, 1984: The town of Griffin Flats is known for almost nothing other than its nuclear missile silos. 16-year-old Laura Ratliff is relieved when she gets a walk-on role in the new film about a nuclear holocaust that is being shot locally. Laura picks her new stepbrother as her plus-one for the film shoot, enraging her fair-weather friends. But their anger is nothing compared to what happens on set after the scripted nuclear explosion. Because nobody seems to know if a real nuclear bomb has detonated or not.
