Yu Zhe, an ordinary food delivery rider, has three major goals in life: running orders, making money, and repaying loans. Until he received an order with the note "slightly spicy, cutlery x1, please write help". At first he thought it was a prank, but in line with the mentality of just watching the excitement, he actually wrote two words on a tissue: Help? As a result, the person who opened the door was a beautiful woman with bruises on her wrists and frightened eyes. The woman took the takeaway and silently mouthed to him: Run. Yu Zhe: "..." I'm just a food delivery guy! Why are you involved in such an urban legend? (╯°Д°)╯ ┻━┻ After the police came to the door, the woman smiled sweetly, saying it was just a joke during the quarrel with her husband, and complained to him for harassment. Yu Zhe was warned and left in despair. But he could not forget that look. From then on, his life was dragged into a whirlpool from which he could not turn back. That address became a restricted area, and there were always cold eyes staring at him from upstairs. The brakes of his battery car were tampered with, and he almost died under the wheel. The only one who believed in him was Chen Miao, a young police officer who had just graduated from the police academy and was full of enthusiasm. Chen Miao: "Where is the evidence?" Yu Zhe pointed to his almost scrapped leg: "Does this count?" Chen Miao: "... It counts as a work-related injury." Yu Zhe: "..." OK, there are no detectives who fell from the sky, only two unlucky ordinary people. A delivery boy and a rookie policeman decided to use the stupidest method to knock on the locked door that hides secrets and sins. They will use their own legs to run around the city.
