A young Zhou Zhi Ping becomes an orphan when his parents died in a car accident. After receiving training from "Santa Claus", he becomes a genius hacker. He sets up Team "Zero" that specialises in stealing and selling confidential information to help their clients solve problems. Concurrently, he is also tracking the whereabouts of "Santa Claus" to uncover the truth behind his parents' deaths.

Si Yun appears to be an Internet celebrity, but she is also a master hacker. She bears a grudge against the swindler, Zi Han, upon exposing his online scams. She attends her best friend, Kai Le's wedding. The groom, Daniel, who has once pursued her but is rejected, pesters her. Zhi Ping, who is at the hotel to track down "Santa Claus", witnesses the scene and helps her out of the predicament.

Si Yun successfully tracks down the IP address of the party who attacks her online, breaks through their firewall and finds out their location. She discovers Zi Han is the attacker, and just when he is being cornered, "Santa Claus" appears and rescues him. While Si Yun is tracking "Santa Claus" down, she encounters Zhi Ping, who is also pursuing "Santa Claus"...

To help young master Shao Guang succeed the chairman position, Zhi Ping successfully influences Director Lu to change his stance from supporting Shao Qiang to supporting Shao Guang instead. With the help of "Santa Claus" on the day of the voting, Director Lu starts to suspect that he is under someone's manipulation and that all the news about Shao Qiang are fake.

"Santa Claus" tells Zhi Ping how he has manipulated Director Lu and declares that Zhi Ping too has fallen into his trap. Zhi Ping remains undaunted. Chairman He wakes up and casts a key vote, supporting Shao Guang to succeed his position. It turns out that he already knows of Shao Qiang's unscrupulous behaviour and hires Zhi Ping to help Shao Guang. "Santa Claus" thus fails his mission.
