There are two worlds, each filled with very different people and perspectives. Who is fortunate, and who is not? Is it Steve, who lives in a world where happiness is forbidden, or is it the rat, who comes from a place where only happiness exists? It soon becomes clear that this apparent happiness isn't genuine at all; it's merely evil intentions in disguise. Yet, everyone is afraid to make a change or take the first step. The rat persuades Steve to join him in this seemingly 'wonderful' world. The boy agrees, hopeful that all his dreams will finally come true, and he will live the life he's always wanted. However, the path to true happiness is not an easy one. Steve, the rat, and their friends must find the courage to become true heroes, uncover the truth, and save everyone. Meanwhile, the Queen of this 'wonderful' world is determined to stop them at all costs. It's uncertain who will survive and who will fall along the way.
