In Linjiang City, Shi Chen is a notorious "black hand". He collects protection fees, ruins things, and even colludes with foreign forces. Everyone despises him. But no one knows that every time he does evil, he is secretly preventing a bigger disaster: he destroys human trafficking dens, collects dirty money from evil bosses, and his contacts with foreign forces are to steal biochemical weapons information. Shi Chen's true identity is a non-staff agent of the country's "Dark Shield" organization. His mission is to sneak into the darkness and protect the light. When a transnational conspiracy surfaced, Shi Chen was misunderstood by the whole world, but he chose to remain silent and use his own way to let the truth become known to the world. This time, he will tear off his disguise and let the entire Linjiang City, and even the whole world, see clearly who is the real 'villain'.
