An act of kindness during a heavy rain caused the gears of courier Lin Xiaoman's destiny to start turning out of place. When he used half a month's salary to advance the medical expenses for a strange old man, he would never have thought that the antique pocket watch stained with muddy water contained the key to changing his class - a Swiss mechanical watch movement from 1789 was valued at over 100 million on the dark web.
From the urban village to the auction house, Lin Xiaoman struggled to break through the squeeze of logistics companies and the hunting of cultural relic dealers. Behind the cooperation invitation handed over by the clinic nurse, there is the end of the logistics company where the husband is paralyzed; the corner of the antique shop apprentice's courtship is reflected in the cold reflection of the surveillance camera; even the complaining customer who was missed on a rainy night actually holds the password to open the third layer of the pocket watch. When the torrent of capital roared in with the warmth of humanity, the young man who helped the old man up in the heavy rain finally understood that what was more difficult than crossing the class was to make the blood-stained gears re-engage the human shape.
