Twenty-four-year-old Su Nian is a gifted art restorer buried under the huge debt her father left behind. Just when her creditors have pushed her to the edge, mysterious billionaire collector Lu Chen appears, buys all of her debt, and forces her into an exclusive contract. If she breaks it, he will destroy what little she has left. Her new job comes with one more condition: she has to move into his isolated private estate.
While restoring a collection of priceless antique paintings, Su Nian starts noticing things that do not add up—smuggled artwork, forged documents, and clues tied to a murder that was buried years ago. Lu Chen is also far more complicated than he seems. He has deep connections to the Russian Bratva and crime boss Antonov, but he is also a longtime undercover informant for the FBI.
As the two test and use each other, real feelings begin to grow. Su Nian goes from being a trapped “restoration tool” to actively joining Lu Chen's dangerous mission, helping him gather evidence against the mob and a corrupt senator. In the end, Lu Chen testifies in court as an undercover witness, Su Nian submits the key evidence, and together they bring down the entire criminal network. Two damaged people meet at the edge of crime and redemption—and choose each other.
