The old blind man has been taking the train from Ningyang to Harbin for decades to look for his daughter, but no one has heard from her. He cried his eyes out and refused to give up. Ma Kui sympathized with his plight and wanted to help him find someone, but After so many years, his daughter's appearance has long changed. The old blind man knew that hope was slim, and he did not want to cause trouble to Ma Kui.
Hou Sanjin accidentally discovered that the theft gang was on this train. He immediately reported it to Ma Kui. Ma Kui rushed into the carriage and saw one of them performing magic tricks with poker, attracting many passengers to watch. The other four took advantage of the chaos to steal the passengers' wallets. Ma Kui and Wang Xin came to the carriage to arrest people. They transferred their wallets and then escaped separately.
Wang Xin chased after the magic thief. He couldn't dodge and fell to the ground, bleeding from his nose. A wallet fell out of his bag. He refused to admit his crime and asked the villain to file a complaint first and frame Wang Xin. A university professor was eating in a dining car during an assault. He questioned Wang Xin's actions. Although Wang Xin explained in every possible way, he couldn't stop the man from messing around. Thanks to Ma Kui's arrest of the other four people, the matter was settled.
The university professor published the matter in the newspaper. Wang Xin was wrongly accused and faced suspension. He was so angry that he was speechless. Wang Yongge came to Captain Hu of the police team to plead for mercy. Captain Hu was helpless and asked him to find the bureau leader to smooth out the relationship. Wang Yongge had no choice but to come to Ma Kui for help and asked Ma Kui to testify for Wang Xin. Ma Kui brought up what happened ten years ago. If Wang Yongge was willing to testify for him, he would not be imprisoned for ten years unjustly. Wang Yongge was disappointed. I had no choice but to leave in frustration. Wang Xin had already guessed that Ma Kui was unwilling to help, and he was very disappointed with Ma Kui.
Wang Sufang begged Ma Kui to testify for Wang Xin, and Ma Yan also begged Ma Kui to speak good words for Wang Xin. Ma Kui refused to let go. Ma Yan was so angry that she refused to take the college entrance examination. Ma Kui was so angry that he could not speak. Yao's mother was worried that Wang Xin would be expelled, so she advised Yao Yuling to break up with Wang Xin, so as not to be implicated and unable to hold her head up for the rest of her life. Yao Yuling was reluctant, and her mother explained the stakes to her, leaving Yao Yuling in a dilemma.
Yao Yuling overheard neighbors talking about Wang Xin's suspension. She was worried, so she came to Wang Xin to inquire about the situation. Wang Xin was waiting for the outcome at home. Yao Yuling thought of her mother's words, and she was completely disheartened. Yao Yuling asked Wang Xin out and broke up with him in person, and Wang Xin stopped pestering him.
When Niu Dali heard that Yao Yuling and Wang Xin had broken up, he went to the store to buy wine and food to celebrate. When Ma Yan heard about this, she came to her home to comfort Wang Xin. Wang Xin gave her a portrait of the big bad wolf and asked her to Passed it to Ma Kui, who saw that Wang Xin was borrowing the painting to scold him. In the next few days, Ma Kui searched for clues and finally found witnesses who were willing to testify for Wang Xin and confirmed that Wang Xin did not hit anyone. Captain Hu sent Wang Xin to exercise at Hongyang Railway Station, which was far away from home.
Wang Xin thought that Wang Yongge's help and trust relationship cleared him from suspicion, so he packed his luggage and prepared to report to Hongyang Railway Station. Wang Yongge knew that Ma Kui had helped Wang Xin, so he brought peanuts to his home to express his gratitude to him, but Ma Kui refused to accept them. Wang Xin took a train to Hongyang and met Ma Kui and his new apprentice Xiao Hu on the platform. Wang Xin was curious about why Ma Kui didn't want to see him.
