The film tells the story of Cristina, a typical Argentine teenager. Her life is suddenly uprooted when she is plucked out of class at the summons of a judge and the couple she knows as her parents are revealed to not be so. In the early \'80s, her biological parents were \"disappeared\" for criticizing the military junta which had taken power in a coup. Surviving relatives of her biological parents, including CristinaÂ’s grandmother, have spent years trying to track down the child. Ordered to now live with her biological family since her adoption--or appropriation, as it is chillingly called--had no legal basis, Cristina begins an investigation of her own in order to find out the truth.
