When his son publicly called someone else “Dad” at kindergarten, Chen Zhiyuan set fire to the custody agreement. He thought he had lost, never realizing that the flames would expose a murder from seven years ago, evidence of his stepfather’s crimes, and a thousand drawings of fathers hidden beneath his son’s bed. When he picked up a hammer at the construction site and refused to stay silent, this battle for his child had long since ceased to be a family dispute. It had become a reckoning for blood debts and the truth. Chen Xiaochuan’s drawings, Grandma Zhou’s mutterings, and Officer Li’s silence were all waiting for him to tear open the hypocrisy of this city.
