Official Website


From 10.00 p.m., Saturdays, 24 July – 21 August 2021



A young woman is kidnapped and her belongings are sent individually to her family. Just about everything is too similar. Zaizen Shota, the CEO of Zaizen Corporation, recalls an uncannily similar case 18 years ago. He had been an investigator at a private detective agency and was asked by a man called Tanioka Soichiro to investigate a case. Tanioka’s daughter was abducted and a piece of her dress, cut up underwear, torn off nails and photos were sent to him. Zaizen is shaken by the similarities of this new case. He owes his glittering life right now with his beautiful wife Yuko to significant tampering he had done on that case 18 years ago. As a result, the criminal was never caught. Now Zaizen’s beloved daughter Mika goes missing and her belongings are sent to him. He is shaken by the very similar cases in the present which are also stoking public fears. On the other hand, Yuko is anxious and has a secret that she cannot tell anyone. Seeking salvation, she starts going to a temple. As Zaizen proceeds to investigate Mika’s disappearance on his own, he begins to learn about Yuko’s past. Is this payback time for his sins of the past? His life starts to go awry … …
