Abandoning the false paradise and pursuing freedom, they faced plants and animals they had never seen before, as well as the "ghosts" chasing them... Although the outside world is beautiful, what they face is too cruel. But the children will not give up. Guided by the message from "Minerva" and a pen left by Norman, they head towards tomorrow. In order to fulfill the promise to meet the "family" who stayed on the farm.
