Bet and Pol are two siblings from Barcelona who move to live with their maternal grandparents near Girona. Their parents have to go to the United States for work reasons. Pol impatiently awaits the arrival of the computer he left in Barcelona to play, but the days pass and it doesn't arrive. The truck transporting it has an accident, and since the address on the box has been erased, an identical computer arrives at the house, which will make them live an unforgettable adventure. With the help of Albert, a young computer science teacher from the institute, they will try to decipher the distressing messages that this mysterious computer sends them. Thanks to their curiosity and perseverance, they will find the evidence that the police need to dismantle an international gang of jewel counterfeiters.
