Ep. 4: Silent Cries

4

Junko Kanno takes her sick dog to veterinarian Yoshiyuki Honjou for treatment, but her dog dies anyway. She later on finds out through the veterinarian's assistant, Masami Sekimoto, that Honjou had not bothered to treat her dog at all, and while looking for evidence, finds that he does not care at all about treating the animals. For both her dog's sake and the other animals, she sends him to Hell. (Source: Wikipedia)
