Following the clues of three missing children, Li Hao met Zhou Jing, who was also looking for his missing brother. As the investigation deepens, they discover that this seemingly peaceful mountain village hides a terrible secret that has lasted for decades: every full moon night, children mysteriously disappear, and this is actually related to a huge human trafficking organization.
When Li Hao tried to uncover the truth, he discovered that the death of his parents was also part of this dark secret. Li Hao must make a choice between the criminal group headed by the village chief, Zhou Jing who hides his identity, and his own desire for revenge. A story about justice and redemption, revenge and forgiveness begins.
