In Hengyang, Hunan Province, Chen Fusheng, a single father with a domineering temperament, worked hard throughout his life to raise his son Chen Xiaojun.
I thought that after my son graduated from college and found a "high-tech" job in Shenzhen, he would be able to "hope for success" in his life. However, what was waiting for him was the sad news that his son jumped to his death from a building, and a vague last letter that mentioned "feet-washing girls", "Macau", "Baccarat", and "I can't pay it off".
In Shenzhen in 2016, there was an undercurrent surging beneath the prosperity and glory. Lao Chen endured his grief, filled with confusion and suppressed anger, and embarked on a lonely journey to find out the truth about his son's death. From the faint trace of blood downstairs in his son's old dormitory in an industrial area to the cryptic words of his colleagues in the "Tengyun Technology" company, one mystery after another follows.
A mysterious woman who had a fierce quarrel with her son, huge debts that could not be paid off one after another, and strange clues pointing to Macau... When the cold words "foot-washing girl" and "Baccarat" gradually became clear, Lao Chen realized that his son's death was by no means a simple accident or work pressure. There was a carefully woven and terrifying trap that devoured human nature hidden behind it.
Faced with the cold social rules and the calculations of human nature, how will this father from a small town rely on his life experience and his fierceness to "not believe in evil" to gradually tear apart the layers of fog wrapped around the truth? When he finally sets foot on the land of Haojiang Casino, what kind of thrilling discoveries and desperate secrets will be waiting for him?
