Wuzhou, a southern mountain city where rain and fog prevail all year round, has a neon-shimmering financial district on one side, and old alleys hiding the old dreams of the Republic of China on the other. Ten years ago, the twin brother Shen Che, the chief prosecutor Shen Yan, disappeared mysteriously in the "ghost alley" of the old city. The official verdict of accidental drowning became an incurable scar in Shen Yan's heart.
Ten years later, Shen Yan was ordered to investigate the illegal land hoarding case of the Lu Group, and met the group's leader Lu Zheng on a narrow road. This ruthless business legend turned out to be the troubled boy who lived near the ghost alley ten years ago, and was the last person to meet Shen Che. The doubts about Lu's family history, the secret connection with the demolition project, and the moment of dispute between Lu Zheng and Shen Che in the photo have re-binded the fate of the two.
An unsolved case that spanned ten years involved the shady story of power and money transactions and the blood and tears of innocent people. The two people with opposing stances were forced to form an alliance through trials and confrontations. While tracing the truth behind Shen Che's death, they were fighting against the mastermind entrenched in Wuzhou. Underneath the cold evidence is Lu Zheng's deeply buried guilt, Shen Yan's paranoid obsession, and the bond between the two that quietly grew in the darkness. What's waiting for them behind?
The fog locks the mountain city and also locks the people's hearts. When the glimmer of truth penetrates the layers of fog, can they get out of this ten-year rain and fog on the road to redeeming each other?
