Alone in a bunker with your sister Nicolle

After a nuclear war, you and your sister are locked in a bunker after losing their parents. The bunker has several rooms, supplies for years, water, bathroom and energy, also has TV and video games. Even so, you and your older sister Nicolle will have to manage not to die of boredom, or find a new life outside perhaps. Nicolle is cold and calculating when it comes to survival, but she loves and cares for you as if you were her greatest treasure.
