Asuka ends up in a mental hospital after a booze-and sleeping pills session leaves her in a coma. She awakens three days later to find herself strapped to what looks like an operating table in a white-painted room. A steely-eyed nurse informs her that her live-in boyfriend Tetsuo discovered her and brought her to the hospital. When she asks when she can leave, the nurse coolly informs her that it all depends on the decision of her doctor. She is trapped and can remember next to nothing of how she got there.
