Five very different urban women were drawn into the bizarre "Fantasy City" because of an elevator accident. During the journey between reality and fantasy, they play various identities: sometimes they are female knights of the mysterious kingdom, sometimes they are wise men of the treacherous chamber of commerce, and sometimes they become sisters in the carefree town. Every time they travel through time, the troubles in reality and each other's shortcomings will cleverly reappear and collide in the fantasy world. They either turn against each other or support each other, or doubt or reveal, gradually uncovering the knots that trouble each other. As the secrets of the fantasy city are gradually revealed, the five people not only gain their sincere friendship with each other, but also complete self-transcendence in the face of adversity and challenges, gaining the courage to grow and reshape their lives. In the end, they work together to reverse their fate, perfectly integrate fantasy and reality, and usher in a rich and sincere new life.
