Light the Dark (把黑夜点燃)

In the late 1990s, in the small southwestern town of Wugang, the Chen family's peaceful life is shattered by a gas pipeline explosion. The father, Chen Fu, dies in the accident, and the mother, Zhang Wenying, is forced to take the blame and later takes her own life. The older sister, Chen Ying (Jiang Xin), remains within the system to secretly gather evidence, while the younger brother, Chen Shan (Chen Zheyuan), leaves home and becomes a rough foreman. After a second, eerily similar explosion occurs in 2001, the estranged siblings must reconcile and work together to uncover the truth, exposing the corruption and power networks behind their parents' deaths.
