On September 15, 2019, an unexpected violent debt collection incident pushed Yu Hai, the owner of a game company, into the whirlpool of life.That night, Yu Hai went to the home of investor Shen Hui with his last hope, trying to save the investment plan that was about to collapse.However, he never expected that what was waiting for him was not only Shen Hui's cold rejection, but also a more difficult problem - Shen Hui's daughter Lu Jie was preparing to run away from home.

Yu Hai witnessed Lu Jie climbing over the wall. Out of sympathy and helplessness, he chose to take in this teenage girl.For Yu Hai, this is a heavy burden and an unexpected turn of events.He tried to communicate with Lu Jie to understand the real reason why she ran away from home, but Lu Jie remained wary and indifferent to him.

On the second day after taking Lu Jie in, Shen Hui clearly rejected Yu Hai's investment request and mocked his dark personality.This blow made Yu Hai feel angry and desperate, and he realized that his gaming career might be in dire straits.What was even more unacceptable to him was that Lu Jie's disappearance seemed to have become an accessory to this failed investment, and was indifferently forgotten by Shen Hui.

Ten days later, on September 24, 2019, Wu Yuke, a new police officer of the Comprehensive Law Enforcement Team of the Criminal Police Team of the Lanshan Responsible Area, received the report.The report stated that a female body was found in the jurisdiction. After confirmation, the body was that of Lu Jie, who had been missing for many days.This news shocked the entire Lanshan City and plunged Yu Hai into deep self-blame and pain.

Wu Yuke and new police officer Miao Jia quickly launched an investigation. They not only wanted to find out the cause of Lu Jie's death, but also uncover the truth behind her running away from home.As the investigation deepened, they discovered that Lu Jie's death was not a simple run away from home or an accidental mistake, but a carefully planned kidnapping and murder.

Yu Hai became one of the key targets of the police investigation. His behavior in taking in Lu Jie and Shen Hui's ridicule and refusal to invest in him became key clues in the case.Under the close investigation of the police, Yu Hai was forced to face his inner fears and struggles. He tried to clear his suspicions and also hoped to find the real murderer of Lu Jie's death.
