Sine is a young female architect who, inspired by the legend of the Seven Sleepers, has designed a unique mosque in the shape of a cave. She is dissatisfied with the current state of architectural practice. However, the construction of the mosque she designed is left unfinished due to various problems. Sine develops insomnia as a result of stress and begins treatment at a sleep disorder center. One day, while sleeping at the center, she has a dream. In this dream, she finds herself within the myth of the Seven Sleepers and witnesses the events unfolding. Upon waking from the dream, she has undergone physical and mental changes, but no one around her notices these transformations. Every time Sine visits the sleep center, she undergoes physical and mental changes. With each transformation, she begins to react differently to everything compared to before.
