The Dark Room tells the stories of three ordinary Germans, each ensnared by the tumultuous events of history. Helmut, a young photographer in Berlin during the 1930s, channels his patriotic fervour into his craft, yet his keen eye fails to comprehend the true significance behind the images he captures. Lore, a twelve-year-old girl, finds herself leading her younger siblings on a harrowing journey across a ravaged Germany in 1945 after their Nazi parents are taken by the Allies.

Half a century later, Micha, a young teacher, grapples with his family's past and the actions of his grandfather during the war. His quest for the truth is met with silence and resistance, and the only person willing to assist carries a burdened history of their own. The Dark Room delves into these individual experiences with profound emotional depth and psychological authenticity, shedding light on the complex and dark moments of the twentieth century.
