In a modern city, a strange elevator accident involves five strange women who can travel between reality and a fantasy world built by each other's memories and dreams. Each time they travel through time, they will be given a new identity and mission. Only by working together to resolve the crisis in the fantasy can they return to reality. As different story lines progress, they face the fetters and pain in reality with multiple identities in the fantasy world. Friendship and love gradually sublimate in cross-border changes and conflicts. The support between them allows them to continue to grow, be honest about themselves, and finally get out of trouble and achieve life reversal. When the illusion dissipated, they had completed their true transformation in reality and became each other's strongest backing.
