When the ship has left Earth three years ago, an asteroid not previously detected hits one of the ship's nuclear reactors, located next to the Cray-5 control module, producing a massive leak of radioactive material, and damaging the host computer. The Cray-5 Superprocessor then decides that it must proceed with the self-destruction of the ship and all its inhabitants, and begins the countdown until the explosion that will end everything.

It is then when you do not hesitate to volunteer for disconnection and subsequent repair, although you know it will not be an easy task, since the numerous self-protection systems installed to prevent sabotage will not make it easy for you. The pulse shakes you when you think about it, but it's not just your life that is in danger. It's about the future of all Humanity, and you can't let it slip through your fingers. You are ready?
