To change the state of his hometown, Heilin Town, Gu Xiaoyu plans to apply for a poverty-alleviation position there. But on the day the results are released, his girlfriend Lu Xiaoxiao, who has always supported his ideals, jumps to her death right in front of him.
"I killed Lu Xiaoxiao."
Several days later, Gu Xiaoyu's father, Gu Zhenmin, says this. The reason is simple: he wants Gu Xiaoyu to inherit his puppet-theater skills, so he hired three thugs to rape Lu Xiaoxiao, then used the photos to force her to kill herself.
Gu Zhenmin claims that if Gu Xiaoyu refuses to voluntarily give up the position during the public notice period and inherit his craft, he will take Lu Xiaoxiao's photos to the police and confess, ensuring Gu Xiaoyu fails the position's political vetting and can never realize his ideals.
He can't let Gu Zhenmin turn himself in. He can't let the world learn that Lu Xiaoxiao was violated. He can't let his dream of poverty alleviation come to nothing.
With these thoughts in mind, Gu Xiaoyu makes a rational yet insane decision.
Patricide.
