In the bustling city, there is an underground organization called "The Experts of Disassembling". When problems that cannot be solved by laws and ordinary social rules arise, it is time for the experts of disassembling to appear. Tu Xinping (Chin Ka Lok) is the leader of the experts of disassembling. Under his leadership, the network-savvy Mai Pingan (Kristal Chu), the legal expert Lei Lei (Mandy Wong), the clever and changeable writer Chen Dawen (Timmy Hung) and the former government official Bai Chun (Lo Chun Shun) show their magical powers in their respective fields. By chance, Tu Xinping met his long-lost brother Mai Xingzhi (Benjamin Yuen) and learned that his mother was seriously ill. When Tu Xinping wanted to return to his family and fulfill his obligations as a son, he found that his identity and status made him very far away from his ideal peaceful life.
