A notorious gang of criminals, under the leadership of the enigmatic "Judge", successfully executed a daring heist on a high-stakes gambling house. Among their ranks was Wei, a skilled car thief who had been supplying vehicles for their illicit activities. Suspicion fell upon Wei when Sir Luo, a senior detective, identified him as a prime suspect in the case. Inspector Zhang Tiezhu, however, was not convinced of Wei's guilt and decided to take matters into his own hands. In a bold move, he released Wei and proposed a tentative partnership, much to Sir Luo's disapproval. As it turned out, Wei was not only involved in the gambling house robbery but also in a recent murder investigation that Zhang Tiezhu was heading. Reluctantly, Wei found himself forced to team up with the police inspector in a bid to clear his name and solve the increasingly complex case. Despite their initial distrust, a fragile alliance began to form between the law enforcement officer and the seasoned thief, as they embarked on a dangerous journey of investigation and betrayal.
