03, a small robot, was busy working day in and day out in a warehouse on the grassland. It was not only the overload of work that it had to endure, but also the violence of its master. One day, in its miserable life, a white horse showed up. Guided by the white horse, 03 made up its mind to rebel. Despite the disintegration of its physical body in the rebellion, its soul followed the white horse, fled to the grassland and gained eternal freedom.
