A couple in a Yonezaki hotel room come to blows, as the man refuses the woman's request. She takes a steak knife from the room service setting and attempts to stab him. The man dodges her attack and leaves hurriedly. The next morning, the body of the woman is discovered, stabbed through the heart with a steak knife. A couple of lawyers step off an overnight bus, having been hired the night before by the prime suspect, Shimazu Kuniaki. Sakata Sadato, a former Yonezaki public prosecutor, grumbles that his assistant, Kosaka Chihiro kept his up with her snoring. As they stroll into town, they are picked up by a car sent by Shimazu. At the jail, they are scolded by Shimazu for not having taken the Bullet train and arrived before today's first trial session. Sakata confronts Shimazu, and demands that he never lies to the duo. At the first trial, a former colleague of Sakata's, Shoji Mao, is in charge of prosecution and seems to have an airtight murder case against Shimazu. Seemingly irrelevant details in the case surface, which leads Sakata and Kosaka to investigate a prior case which involved the victim, Hamada Mitsuko, her ex-husband, a GP doctor, their son, and Shimazu. Witnesses for the defense are found, and a different picture appears, until the final witness' testimony (and lack of it) reveal that Justice has been subverted.
