A global cataclysm, caused by a fatal accident in Geneva (Switzerland) during the implementation of the particle accelerator will lead to the crew and students of the school-ship Polar Star to live the greatest adventure of their lives. Isolated and aware that we only have each other, the ship will become their only home.

Luis never acted as a father, and now that he should and wants to, he can't. Kike always runs from responsibilities, and now he's faced with his biggest one yet. Girón, a ruthless lawyer, and Curro, a professional schemer and owner of the neighborhood bar where they both grew up, will be their advisors. Lola, a social worker as strict professionally as she is insecure personally, will also appear and closely monitor the children's upbringing. An atypical, modern, and "connected" family.
