Tim and Paulina are robbed already on the first night of their trip to the Baltic Sea, The thief: a 12-year-old boy. But not a common boy, rather one who insists that he is a clone and has fled from a secret boarding school for the highly gifted. He implores Tim and Paulina to help him, because the training centre's security is hard on his heels. The two first think that this is silly craziness, until they are suddenly pursued and finally reach the interior of the boarding school. They face one question there: How will they get out again? Because the hours are number for those who know.
