Gu Yan is the captain of the criminal police brigade, with the highest crime detection rate in the city. He only sees evidence and never admits defeat.
Fu Sihan is a legend in the world of criminal defense lawyers. He has been undefeated for ten years since his debut. He specializes in sending out of court those who Gu Yan worked so hard to capture.
When two people meet, they fight each other, they argue in court, and they snort when they pass each other in the corridor.
Everyone knows that Gu Yan and Fu Sihan are naturally opposed to each other.
Until a serial business fraud case was placed in front of Gu Yan - with as many as 300 victims, the mastermind behind the scenes was hidden in layers of corporate structures, the chain of evidence was artificially cut off, and her investigation hit an invisible wall every time.
The boss handed her a business card: "To investigate this case, you need someone who understands business law."
There are three words printed on the business card: Fu Sihan.
Gu Yan stared at the business card for a long time, and finally knocked on the door of Fu Sihan's office with it in hand.
He raised his head and slightly curved his mouth: "Captain Gu, please beg me?"
She gritted her teeth: "Cooperate."
From then on, the bitter rivals became partners, one was in the open and the other was in the dark, one was chasing people and the other was looking for loopholes. While working together day and night, Gu Yan discovered that Fu Sihan never defended the real bad guys; Fu Sihan discovered that every file written by Gu Yan was full of fight to the end.
Neither of them realized that a certain wall in their hearts was collapsing little by little.
Concept: Caught between rules and justice, two people who each adhere to one side learn to understand each other's boundaries, and find the deepest resonance in opposition.
