In the center of the plot is the police captain, detective Marianne Aubris, who is leading a high-profile case of a robbery. At this moment, a child psychologist turns to her with the story of a little boy Malone, who believes that his mother is not really his kin. The situation seems suspicious also because Malone clearly knows more, but cannot tell about it, fearing his mother’s anger. The words of a three-year-old child can turn out to be both a child’s invention and a reason for a real deed. Should a detective believe the boy and start a case that will shed light on mysterious events?
