A human undergoes a procedure to transplant her consciousness into a spaceship, though her actions are held under strict protocol. After she befriends a vulnerable child stowaway onboard, she decides to take back control of the ship.

Aboard a human city ship headed for Proxima b, shadows begin to haunt the sleeping passengers. An engineer commits suicide, and a psychotherapist finds that these apparitions feed on human guilt. The only way to survive is to master and confront the mounds of guilt that each human passenger carries inside herself.

On a distant planet, in a former thriving metropolis, the ghost of a temple cat tries to defend the ruins of her city against an evil intergalactic force.
