The criminal series goes back to Season 6, where investigators are investigating the death of a man who accidentally killed in the park without knowing the killer. Meanwhile, Bobby's tests reveal that his heart is damaged, as the only option seems to be heart transplantation. On the other hand, investigators are returning for an interview with the suspect, who initially gave them misleading information. The suspects discovered that the suspect provided information because they were trying to protect themselves from the actual perpetrator.
