As governments scramble to control the truth and society fractures under the revelation, a group of strangers is drawn into its centre: a journalist-meteorologist (Emily Blunt), a political insider (Josh O’Connor), a veteran statesman (Colin Firth), a determined reporter (Eve Hewson), and a crisis leader (Colman Domingo). Their lives converge as humanity confronts its most consequential discovery.
