First instalment of an epic trilogy of live action films based on Naoki Urasawa's manga series 'Yawara'. 30 years after they whiled away the long days of the school holidays by playing at being crime fighters, Kenji Endo (Toshiaki Karasawa) and his friends find that their lives are about to be changed for ever. A series of unexplained deaths and the rise of a strange religious cult seem to be recreating the games that Kenji played with his friends all those years ago. At that time, they wrote down the storylines of the games in a 'Book of Prophesies'. Now those prophesies seem to be coming true. Unsure of what is happening, Kenji reforms his childhood gang and sets out to discover what is going on.
