Han Linghe (Shou) is a genius in science. He suffered a lot when he was young and was involved in a secret organization.
By chance, he met criminal policeman Yang Feng (Gong) and was attracted to him. With a new identity, Han Linghe stood beside Yang Feng and solved many cases side by side.
However, Han Linghe's behavior harmed the interests of the organization. The organization uncovered his past, and the two people who used to be side by side were forced to stand on opposite sides.

In the darkness, they waited for belated reunion and redemption.
