The film tells the story of Su Jianming, an ordinary young policeman who works at the Municipal Bureau's Criminal Identification Center.

To investigate the truth behind a bus explosion case, Su Jianming defies the warnings of his powerful and influential father, Zheng Gang, and rushes to attend a banquet hosted by wealthy businessman Li Zhitian.

There, Su witnesses Li's brazen and cruel display of power, which includes humiliating others and plunging his hand into a boiling hotpot.

As the night unfolds, shocking clues gradually surface: a corpse hidden in a wall, a deadly assault with a wrench, and the under-the-table transfer of nearly ten billion yuan.
