The movie has three separate stories that are connected through a murder that takes place at the beginning in a suburban neighborhood in Tokyo. A mysterious man, whose face we never see, brutally murders a married couple in their home and paints the word “rage” on the door their blood. Detectives Kunihisa Nanjō and Sōsuke Kitami investigate the double homicide and discover that the perpetrator has gone through plastic surgery to escape the authorities. Then, we are shown the lives of three young men living in different parts of modern-Japan who might be the murderer. In Chiba, a reclusive newcomer Tashiro Tetsuya arrives in town and befriends Aiko, a problematic young woman who was working in a brothel for a few months. She had only recently returned to her hometown after her father, Maki Yohei following an incident with a customer that left her traumatized. Tetsuya is the only person in town who can accept Aiko despite her dark past and Maki blesses their relationship. However, he begins to suspect that Tetsuya is not who he says he is after realizing that he is lying about his past. Aiko then reveals that Tetsuya is actually on the run from the Yakuza who are after him for not paying his dead father's unpaid debts. However, Aiko herself starts to suspect Tetsuya is not telling the truth after realizing that he looks strikingly similar to one of the sketches of the murderer. The second story revolves around Onishi Naoto, who hides out at a gay bathhouse in Tokyo to avoid people. One night, he is approached by Fujita Yuma, an openly gay man. Naoto resists Yuma at first, but Yuma holds Naoto down and they have rough sex. Then, Yuma takes Naoto out for dinner and learns that he does not have a place to stay. Yuma offers to let him stay with him until Naoto finds a permanent place and they both become housemates. They slowly fall in love and Yuma even introduces Naoto to his sick mother and his other gay friends. When Yuma's mother dies, Naoto comforts him and they become even closer. However, Yuma sees Naoto with an unknown girl at a cafe one day. Yuma also starts to realize that Naoto resembles another one of the police sketches of the murderer. When Yuma confronts Naoto about this, he does not give a direct answer and instead leaves their apartment the following morning. The third story is about Tanaka Shingo, a free-spirited homeless young man who lives alone on an abandoned island near Okinawa. One day, a teenage girl, Suzuya Izumi, moves into the town with her single mother. She makes friends with a local boy, Chinen Tatsuya, who has feelings for her. One day, while exploring the island, Izumi meet Shingo and they strike a friendship. One night, the three accidentally meet in Naha. Tatsuya, who gets drunk, is momentarily separated from Izumi, who tries to search for him. Instead, she gets brutally raped by two American soldiers from the nearby army base. Tatsuya sees this but is too scared to fight off the soldiers. After the soldiers leave, Izumi makes Tatsuya promise to not tell anyone what had just happened. Meanwhile, in Chiba, Aiko starts to fear for her life and eventually calls the police, but not before tipping off Tetsuya. Tetsuya runs away before the detectives arrive to test his fingerprints. The forensic tests reveal that he is not the murderer. Aiko becomes unstable again as she fears she has lost the one man who would ever love her forever. However, Tetsuya calls her one last time and Maki manages to convince him to come home. Although Aiko now is happily reunited with Aiko, Maki has to live in fear for the rest of her life that his daughter's life will forever be in danger because of Tetsuya's dark past. At the same time, Yuma meets the girl Naoto was talking to at the cafe. As it turns out, Naoto grew up in a facility for orphans with health issues. The girl grew up in the same facility and she is the closest thing to family that he has. She reveals that Naoto has been living in the closet his entire life and he fell in love with Yuma because of his confidence and courage. However, he became heartbroken after Yuma starts questioning about his past. He left their apartment and died because of a heart attack. In Okinawa, Tatsuya arranges for Shingo to work at his family's hotel. Shingo reveals to Tatsuya that he in fact witnessed the rape himself but was also too scared to take any actions. One night, they both reveal to each other that they both saw Izumi being raped by the Americans but were both scared to do anything. One evening Shingo suffers from a sudden fit of rage and escaped back to the island. The following morning, Tatsuya goes to meet him there and finds the word "rage" scratched onto the wall, although he does not know what it means. In the end, Shingo confesses that he actually saw the Americans ogle at Izumi and shadowed them as they followed her. However, he did nothing to warn her because he wanted to see her raped. Tatsuya suffers a breakdown after discovering the truth and ends up stabbing Shingo in the stomach before calling the police.
