Warsaw, three eras, one cursed tenement. In 1937, Stanisław Kowalski discovers remains of a murdered family in the basement and makes a fatal decision to cover up the crime. In 1983, his son Jerzy struggles with ghosts of the past during martial law, when a secret police officer begins sniffing around the building's secrets. In 2003, granddaughter Anna returns to the family tenement to solve the mystery of the missing remains and break the family curse. Stephen King-style psychological horror where Polish history merges with supernatural phenomena, and victims' spirits demand justice across generations.
