When his sworn brother Sun dies by suicide, Brother Six settles his debts at the funeral and takes possession of a mortgaged Rolls-Royce, only to discover that its license plate belongs to Shen Yichen, the son of the chamber of commerce president. Insisting that debts must be repaid, Brother Six confronts the Shen family head-on. The Shen family repeatedly suppresses him and even causes Sun's death. Brother Six joins forces with his former subordinates, persuades Lu Wentao to switch sides, and launches a three-pronged counterattack using the law, public opinion, and Shen Nanfeng's father-son bond. Ultimately, he submits evidence of Qi Huairen's corruption, brings down the powerful, and avenges his brother.
