Tamami (Esumi Makiko) is a shrewd forensic pathologist who boldly acts according to her own convictions. She would do whatever it takes to reveal the truth behind the deaths of victims who have no voice, and pays no heed to the objections from those around her. But at home, she has trouble with household chores and communicating with her son, which makes her feel torn between work and family. Chika (Ishihara Satomi) is a career detective who does nothing at the police precinct. She wants success in work as well as marriage, but her life spins around in aimless circles. Even though the two of them face off each other over strange, unnatural deaths and get into conflicts because they are the least compatible, they unravel these mysteries as if they are speaking for the dead.
