Just after level-headed paramedic David 'Dave' Vaughn learns he's to become the father of a son, he and his gullible colleague Victor 'Vic' Hernadez are called away for an emergency at a gas station. After they diagnose Rebecca with a seizure, a truck of armed men in white, like her, arrives. They prevent her being brought to hospital and abduct the paramedics to a compound. It's run by the Teacher, founder and absolute leader of a 'scientific' cult, the Quanta, promising its members the Formula will save them during the impending apocalypse by fire from the sky. Superstitious Vic is immediately terrified and his Catholic faith brainwashed. Dave resists, escapes, is captured, and is electrocuted as 'crash initiation'. Will he survive and save others?
