The seven doors

University professor Nina is at a turning point. Her work seems increasingly irrelevant, her doctor husband is never home, relations with her difficult daughter are strained, and their beautiful house is scheduled for demolition. When she discovers that she and her husband still own a house that she thought had been sold years earlier, things take a very dark turn. The young woman living there disappears, leaving her son behind, the day after Nina and her daughter pay her a visit. With few clues, the police enquiry soon grinds to a halt, but Nina has an inexplicable sense of guilt. Unable to rest, she begins her own investigation, but as she pulls on the threads of the case, it seems her discoveries may have very grave consequences for her and her family.
