"Legally, we are mortal enemies. Secretly, we are accomplices."
On that rainy night seven years ago, Wen Lin held Jiang Xun's hand and pulled the trigger, but the bullet was fired into their common future. He was awarded the "Badge of Justice" and she was convicted and imprisoned.
Seven years later, the medical anti-corruption storm swept across the city. He is the ace lawyer of a top law firm, vowing to uncover the medical shady story; she is the chief legal officer of a multinational pharmaceutical company, and is ordered to build a strong firewall. When they meet again at the negotiating table, every exchange of legal documents is a test, and every exchange of eyes is asking: "Will you still keep that secret for me?"
And when a deeper conspiracy targeted both of them, they discovered that the bullet casing from seven years ago was not only the evidence of conviction, but also each other's only life-saving talisman.
