In Rockford, Illinois, local resident Logan Lewis is reported dead along with 41 others in a Los Angeles house. The government attributes the deaths to an unreported uranium mine. The victims, suffering from radiation exposure, have been taken into custody, and the house is destroyed. Grief-stricken, Devan travels to California with her childhood friend Nate to confront Logan's death. Nate, drawn into a larger mystery, brings along his friend Brandon to film the events. They discover something far stranger than they could have imagined: not everyone in the house is deceased.
