Tormented by recurring nightmares of a mysterious place she’s never been, Marlene (Sandra Hüller, REQUIEM) cannot help but investigate when she discovers the place is real. Once there, she suffers a breakdown and is admitted to a psychiatric ward. Determined to discover what happened, her daughter Mona (Gro Swantje Kohlhof) follows and finds herself in Stainbach, an idyllic village with a dark history. What is it that so tormented her mother and the people of Stainbach? What is the source of the nightmares she suffers? And who is the mysterious Trude that lives in the forest? Richly conceived and confidently told by director Michael Venus, SLEEP claws its way down to the roots of what haunts a people, a community, a nation and comes up screaming.
