In a world of fantasy, siblings go on a mission to find the parents who raised them. They jump into a gate, hoping to end up where their parents went. But they didn't. Instead, they have reached a place where robots have taken over the world and humans are going extinct. Robots guard the territory to keep out intruders. Because the secrets in those causes could not be discovered by humans. The mission has failed, and they have been spotted. They return to their world, ready to find another way to save their parents. Unfortunately, they will need to stay together and work as one, or else the future will be scattered. Will siblings find the parents they raised? Will they return to them even if they abandon them? Or will they get stuck on the other side of the world and never come back?
