"On July 14, a corpse sealed in cement was found at the construction site of the playground of No. 1 Middle School in our city. The police are investigating further details. Provincial leaders attach great importance to this and have set up a special investigation team for the "July 14" playground burial case to go to our city to assist in the investigation."
During a construction project, an astonishing truth that had been sealed for 16 years finally came to light.
"Check it for me! Check it carefully!"
"Don't be afraid, I have everything."
The showdown between good and evil begins...
"Team Leader Wang, I believe that the law will not wrong any good person."
"Miss Gu, you are right, but the law will not let any bad person go."
"Really? I hope..."
How many unknown secrets are hidden behind the corpse burial in the playground?
"There must be some truth that we haven't discovered yet."
"The water in Songshan City is too deep..."
"I just want justice, justice that is 16 years late. I just want justice for my mother!"
"Zheng Guoqing deserves to die, he deserves to die!"
Dawn will eventually come, and when the first ray of sunshine shines on the earth, it means that the darkness has passed and the sins have been washed away.
"I don't regret it. Now, I'm really relieved. I'm so tired..."
"Liang Zhengyang, thank you, and... I'm sorry..."
Before dawn, the mystery is revealed.
Look, it's dawn...
