Set during the Republican era, The History of Crime revolves around five cases that are interconnected in some way. A detective, a thief and an undercover who have proven to be exceptional in their own fields combine forces to fight crime. A series or murders have stumped the police force, leaving them no choice but to ask for the help of Xiang Long, Qian Kong and Lan Ruoxin. The three geniuses who are a detective, thief and undercover with many faces start out at odds with each other, but eventually learn to work as a team. Just as they pride themselves for cracking the case, a greater danger looms.
