"Brawurowy podwójny portret młodego mężczyzny, jednego z najbardziej znienawidzonych i brutalnych norweskich kolaborantów w czasach okupacji niemieckiej, oraz ocalałej z Holokaustu żydowskiej rodziny, która po wojnie zamieszkała w jego domu - niemym świadku zdarzeń." -- Once the Germans conquer Norway in 1940, they quickly discover a tremendous native asset: Henry Oliver Rinnan, a double agent so cruel and manipulative that he would become notorious as one of Norway's vilest traitors, second only to Quisling himself. In 1941, Rinnan and his gang set up headquarters in an unspectacular suburban house and transformed the cellar into a makeshift torture and death chamber reserved for Norwegian resisters. In the war's aftermath, this house became home to a Jewish-Norwegian couple still reeling from trauma. Many decades later, Simon Stranger married the daughter of one of those girls, and, learning the history of her family, soon realized that their story could not be told without including Rinnan's.
