On that night when his clothes were stained with blood, Gu Lin shot the traitor through the chest with his own hands, but could not save Li Zheng's left eye. Seven years later, he was reduced from a special operations captain to a prisoner, and Li Zheng was already standing at the highest position with the blood-soaked badge on his chest. When the armed forces raided all night, the order was issued: "Only capture Gu Lin alive, don't hurt him." Li Zheng walked into the smoke, and the man who had taken three bullets for him reflected in his eyes - this time, it was his turn to use his life to pay off the betrayal that should not have happened.
