Six years ago, bus driver Zhou Jianguo ran a red light to rush Liu En, a young woman suffering an unexpected brain tumor crisis, to the hospital. Instead, she reported him, costing him his job and leaving his family disgraced. Six years later, Liu En passes a series of rigorous selection rounds and enters the final interview room of his son-in-law, Lu Mengchuan. Lu tears up her contract and refuses to hire her, but Liu En reveals a camera hidden in her brooch—the livestream has already set the internet ablaze. She carefully turns the rules against him, forcing him to apologize and dragging his father-in-law into the confrontation. Then a flaw emerges in a jointly signed petition, followed by a sudden bombshell: an in-car recording reveals that Liu En was never unconscious that day. Who is lying? Who has been pulling the strings? Whom will the blade of rules ultimately strike?
