Ke Xiaonan, a passionate young man, resolutely devoted himself to the cause of public security criminal investigation. He devoted himself to protecting the country and the people, and went through all kinds of difficulties and dangers. In a large-scale mass incident, Xiaonan was injured and hospitalized to save his comrades. As a result, he met Luo Yudan, a beautiful doctor who was crazy about pursuing him. At this time, Xiaonan already had a crush on him.
In a fierce and unusual battle between police and robbers, Xiao Nan killed the gangster. The deep longing for his dead comrades made him do something stupid on impulse, and he was imprisoned for it. This incident caused a sensation across the country. The people he loved did not know the truth and began to criticize him verbally and writing. Xiaonan became the target of thousands of people for a while.
The wise comrades pooled their wisdom and efforts to turn the tide. Business tycoon Luo Yi generously donated money to save the hero. After being acquitted, Xiaonan accepted the instructions from his superiors and went undercover, and his entire life trajectory was rewritten.
Luo Yi was retaliated by gangsters and his life was in danger. In order to save the life of his benefactor, Xiaonan took the treasure map left by her grandmother and resolutely broke into the underground palace and ghost house, bravely waded into the White Tower and Black River, and obtained huge wealth in the thrilling danger. It was precisely because of this wealth that Xiaonan was imprisoned again.
After being released from prison, Xiaonan once again went deep into the ghost house. He accidentally discovered a letter and a rope that had been sealed for many years. Because of this rope, he pulled out an injustice in the past and a historical tragedy.
