This is a cruel experiment on "what it means to be human". When the body grows feathers, when the reflection in the mirror turns into a bird, when the dearest relative becomes a beast pecking for feed, the boundary between the prince and the prisoner collapses. Under the steel sky full of barbs, in the viscous nutrient solution pipes, the glimmer of humanity and alienated instincts fight to the death. And the human silhouette projected when the two moons overlapped, became the cry of the soul that penetrated the dimension - even if the body is reduced to an experimental number, free will will never surrender.
