Plot:
One night, Tsuchiya Tetsuyo (Emoto Tasuku) suddenly woke up in the company's meeting room and returned home as usual. His wife Chika (Suzuki Anne) looked strange and frightened. His son, who should have been 1 year old, woke up, but he looked 4 years old. Soon an official came to visit him and said, "You have been dead for 3 years." TV and the Internet are full of news about people who should have died resurrected all over the world. But Tetsuyo has no memory of death. Although he said he fell from the roof of the company, he has no personal experience of either accident or suicide, and he can't let it go. Was he killed by Saeki (Abe Takashi) who pestered him at every turn when he was alive? Saeki, a security guard at Tetsuyo's company, vents his resentment for the level gap and loneliness on Tetsuyo and harasses him repeatedly. Faced with an increasingly deep mystery, Tetsuyo pursues the answer. But Chika seems to be hiding something.
