Yoshimi Matsubara and her ex-husband are engaged in an uphill battle over the custody of her five-year-old daughter Ikuko. Despite her psychiatric past, she hopes to be stronger by finding work and renting her own apartment. However, due to her work, she will occasionally have to neglect her daughter and in addition there appears to be a large damp spot on the ceiling of the apartment and the caretaker is an old, lazy man. As her stay progresses, the place starts to get bigger and Yoshimi also finds a red children's bag on the roof of the building that she can't seem to get rid of. Also, Ikuko begins to behave more and more strangely and she gets an "imaginary" girlfriend, who may not be as imaginary as it first seems.
