When Dr. Nagashima loses his wife in a myserious car crash, he is overwhelmed with grief but also an eerie sense of purpose; he becomes obsessed with the idea that he must reincarnate his dead wife. Her donated kidney is transplanted into a girl with a debilitating disorder, but the doctor also feels compelled to keep a small sample of her liver in his laboratory. When these cells start mutating rapidly, a consciousness bent on determining its own fate awakes from an eonic sleep.
