The film is divided into 5 chapters, the first four of which are named after characters in the film: Noriko, Yuka, Kumiko and Tetsuzo, in that order. The plot is told non-linearly and shifts between the perspectives of Noriko, Yuka and Tetsuzo. A shy and demure 17-year-old girl named Noriko Shimabara lives with her quiet family, formed by her sister Yuka, her mother Taeko, and her father Tetsuzo, in Toyokawa, Japan. Noriko finds her small-town life unsatisfying and craves to move to Tokyo, assuming she would live a more active life there. This sentiment is especially encouraged when she finds that her elementary school friend Tangerine is now working independently as an idol. Noriko's father is strictly against her going to the city, and plans on having her join a local university after school. Feeling alienated and misunderstood by her parents, Noriko resorts to the internet where she finds Haikyo.com, a website where other teenagers from Japan gather. There, after making new and unknown friends, she feels truly at "home" and eventually, on December 10, 2001, runs away from her unhappy life to Tokyo, where she plans on meeting the website's leader, a mysterious girl who uses the screen name "Ueno Station 54". Once in Tokyo, Noriko logs onto the website and contacts Ueno54. They meet up at Locker #54 in Ueno Train Station, where it is revealed that she is a young woman named Kumiko. Kumiko introduces Noriko to her family and takes her to visit her grandparents. As it turns out, however, Kumiko has no real family, and the people she introduced Noriko to are paid actors working for Kumiko's organisation, I.C. Corp. The organisation offers paid rental family services to interested clients, allowing them to fulfill their fantasy of a happy family life. Six months later, 54 girls jump in front of a train at Shinjuku station and commit suicide while Noriko and Kumiko look on. It is implied that the 54 were members of the organization acting out their roles. Back in Toyokawa, Yuka, who was also a member of Haikyo.com, wonders if her sister was involved in the mass suicide. She writes a story speculating how her father would react if she were to disappear as well, and deliberately leaves clues before running off to Tokyo to join I.C. Corp. Tetsuzo attempts to put on a brave face after Yuka's disappearance, but his wife Taeko's mental condition deteriorates rapidly and she eventually commits suicide. Meanwhile, Tetsuzo, a reporter, gathers clues regarding his daughters' disappearances and discovers Yuka's story. He is crushed to find that his daughter could predict his actions and behaviour so accurately while he was completely unaware of his daughters' feelings. His investigations reveal Haikyo.com and taking a cue from sensationalist media tabloids, he concludes that his daughters are part of a cult called the "Suicide Club". Tetsuzo contacts a member of I.C. Corp, who refutes the existence of a "suicide club" and instead expounds on a concept of social roles that forms the basis of his organisation. Tetsuzo gets an old friend of his, Ikeda to pose as a client for I.C. Corp and rent Kumiko as his wife, and Noriko and Yuka as his daughters. Tetsuzo finds a house in Tokyo resembling his own and moves all the furniture from the old house to the new one so that it will resemble it exactly. Mitsuko and Yoko are unsettled when they arrive at the house, but they fall back into their roles when prompted by Kumiko. Ikeda sends Kumiko away on an errand and Tetsuzo reveals himself. The girls, however, treat him as a stranger and insist that they are Mitsuko and Yoko, not Noriko and Yuka. As the session falls apart, thugs from the organisation arrive on site to beat up Tetsuzo, who attacks them with a knife and kills all of them in the living room. Kumiko arrives from her errand shortly thereafter, playing out her role as if nothing is wrong, but then imploring Tetsuzo to kill her and run away with Noriko and Yuka. Her insistence gravely disturbs Noriko and Yuka, before Yuka interrupts the heated conversation and asks to 'extend the session'. Finally, Tetsuzo, Kumiko, Mitsuko and Yuka dine together as a happy family and Tetsuzo begins acting as if Kumiko is his wife, calling her Taeko. Yuka does not sleep that night and leaves the home at the crack of dawn, shedding her role and name. Mitsuko awakens shortly thereafter and, speaking to herself, bids goodbye to Yuka, adolescence, Haikyo.com and Mitsuko, before finally declaring that she is Noriko. By the end of the film, two years have passed, including eighteen months since the mass suicide.
was written by Sion Sono in April 2002. This book was a draft of sorts for Noriko's Dinner Table, according to Sono. In fact, the movie is divided in four "chapters", like the book, and is constantly narrated by its characters, like the book. The story of The Complete Edition deals with both the events of this film and those of its prequel, Suicide Club. So far, no plans for an English edition have appeared.
