In the 1960s, a young girl is institutionalized by her abusive stepfather at the Lennox House for the Mentally Insane after she accidentally kills her younger sister while trying to protect her from him. Facing a lobotomy that will erase her troubled past and an unwanted reality, the girl retreats into an alternative fantasy world as a coping mechanism. Within this vivid dreamscape, she transforms into a dynamic and powerful version of herself, meeting four other girls who become her allies. Their world is a distorted mirror of the asylum, where they are trapped as dancers and entertainers under the watchful eye of the establishment's corrupt manager.

Within the layers of her imagination, the protagonist plans to escape both the fantastical dream world and the real-life asylum. She visualizes a series of high-stakes missions, each providing an item necessary for their freedom. In this alternate reality, the girls engage in epic battles against various fantastical enemies, drawing parallels to their struggles within the asylum. Each victory in the fantasy domain represents a step closer to their goal of escaping the physical and mental prisons that contain them. They must rely on each other's strengths, facing fear and adversity, as their shared plight binds them in a desperate fight for survival.
