The film is adapted from a real incident. A single working-class woman, Christina, left her child at home due to overtime work. After returning home, her son disappeared. The police first refused to accept the report within 24 hours, and then the case has been delayed. It was not until 5 months later that the police suddenly told Christine to help her find her son, and brought a team of media to the train station to pick him up. Although Christine knew that the boy was not her son at the time, the little boy repeatedly insisted that it was her son, the police. Chang also tried his best to persuade that he may have been away from his son for too long to recognize him. In this way, the newspapers were full of news of mother and son reunion, and the Los Angeles police also saved some face. But Christina, based on her height, foreskin, and the judgment of the dentist and teacher, determined that the child must not belong to her. She hoped that the police would continue to search for her son, but was refused and was sent to a lunatic asylum as a mental illness.
Christina then discovered that many women here were detained for confronting the police, and they could only be released if they ensured that they would not cause trouble again. They used power to cover up the truth and fully demonstrated the police's discriminatory and injustice against women and their despicable practices. Fortunately, Gustav Briegleb, the pastor who has always despised the police, and the prostitutes of the mental hospital who were treated equally by the police, and many people who were also dissatisfied with the police helped Christine go from being a weak and helpless woman to standing in court. The Los Angeles police fight against the fighters of the thin court. On the other hand, the whereabouts of his son was gradually revealed due to the arrest of a perverted killer. The son had a chance to escape, but he returned to the killer's farm in order to help the other partner who fell. In the end, the state government repealed the 12th law that allowed Christina to enter a mental hospital, and the chief of police was demoted and the sergeant was permanently removed. Christina has been searching for her son all her life, but she did not find her until her death.
