Ye Feibai once managed to leave a mysterious organization and return to an ordinary life. But a mysterious text message drags him into a heart-pounding crisis. What begins as an assassination mission suddenly turns into a mission to protect a girl and an important recording, sending him on the run as men in black hunt him relentlessly.
During the escape, Ye Feibai reunites with his former partner, Lin Yu. Mistaken by the organization for a mole, Lin Yu has joined a righteous organization. The two team up with a scar-faced man and narrowly escape death, only for Qingwan's tracking device to expose their location and plunge them into a deadly fight. They finally manage to get away, but Lin Yu is captured by the men in black. Ye Feibai and the others venture back into danger to rescue him and obtain irrefutable evidence of the black-clad leader's crimes, helping the police take down several of his bases.
However, the leader does not surrender. He goes into hiding instead. Drawing on his indomitable will and exceptional intelligence, Ye Feibai eventually finds his hideout. But when he, Lin Yu, and Qingwan set out with confidence to defeat him, they are trapped in a warehouse, their fate unknown.
In this battle between good and evil, can they overcome every obstacle, completely foil the men in black's plot, and protect justice and peace?
