In a daze, Junko agreed to the president's private request to help investigate the secret room death case of the president of New Japan Funeral Club. On Serizawa's side, due to Junko, he was accidentally imprisoned in the bank's vault. While everyone was in a state of distress, Enomoto Kei (played by Satoshi Ohno) from the security company completed the impossible task and opened the door to the vault with superb technology. Junko, who was full of curiosity, asked Enomoto, who was interested in the secret room, to participate in solving the secret room death case. So Serizawa, Junko and Enomoto formed a trio of secret room murder cases, and one after another they solved various secret room murder cases by mistake, and the locked rooms were opened one by one. Enomoto, who is taciturn and dedicated to studying door-breaking and lock-picking, has also gained the trust and love of Serizawa and Junko in a series of cases. What ulterior secret seems to be buried behind Enomoto?
