Director Amit Gupta teams with Welsh author Owen Sheers to adapt Sheers' gripping novel set in 1944 in an alternate history where the Nazis have occupied areas of Britain, and a small Welsh village is about to awaken to a shocking surprise. All of the men in the village of Olchon have vanished without a trace, including Sarah Lewis' (Andrea Riseborough) husband Tom (Michael Sheen), a respected farmer. Could they have left under the shroud of darkness to join the Resistance? As the women nervously ponder the fates of their absent husbands, a German patrol appears in Olchon on a clandestine mission. When the winter weather takes a turn for the worst, the local women and the German troops are forced to rely on each other for survival.
