Seven years ago, the talented girl Lin Anran was forced to "die" after a car accident targeting the Lin family; seven years later, she returned to China as Narna, the world's top hacker, and was stopped at the airport when she landed at the airport by her former deskmate Song Qian, now a technology upstart. She wanted to use the security authority of Shi'an Technology to find out the truth about her mother's death, and Song Qian wanted to use her ability to deal with the company's hidden crisis. The two cooperated in the name of trading, and through old love, lies, data and blood, they uncovered the truth about the car accident and the Longteng Group layer by layer.
