Sagara Ryosuke is an ordinary salaryman who works for the customer service department of Kameda Transportation, a mid-size transportation company. A good-natured and easygoing person, he has a charming wife Maho. The close couple have a daughter in the second year of high school, Hikari, and younger son in elementary school, Atsuto. They live in a housing complex and are looking forward to the completion of their dream home which is being built in the suburbs. The Sagaras were supposed to be a happy family until Ryosuke comes back from work one evening to discover that Maho and his two children have suddenly vanished. They cannot be reached on their mobile phones and he notices that Maho had set the timer for the rice cooker to cook rice before she went out. When Ryosuke alerts the police, he is told that there is no urgency as there is a possibility that they have run away from home. He gets no clues even after going round to the supermarket where Maho works part-time as well as the schools that Hikari and Atsuto attend to talk to people. At his wits end, Ryosuke consults his good friend Kawamura Toshio who is the chief editor of a weekly magazine. Sensing that foul play maybe involved, Kawamura suggests that if an article is written and attracts attention, the police may take action. Ryosuke feels disconcerted but takes up this offer. He is pushed into the spotlight and garners sympathy when his family’s disappearance comes to light. However, once the public’s eyes are all over a case, the story takes on a life of its own as people use whatever information is available to make their own deductions and come up with the background. In the blink of an eye, Ryosuke turns from tragic husband to suspicious husband due to a certain social media post. Despite being flagged as the real culprit who killed his family, Ryosuke tries to find the truth and get his beloved family back with the help of his subordinate Ninomiya Mizuho at work.
