Kim Sun Joo, the brilliant founder and CEO of one of the nation's largest IT companies, is a name everyone knows. With a genius mind and a life of success, he seems to have it all—but living at the top comes with deadly risks. When an unknown assassin targets him, Sun Joo falls victim to a brutal murder. However, instead of crossing over, his spirit inexplicably finds refuge in his smartphone.

Trapped within the device, Sun Joo might have been doomed to an eternal digital prison if not for Park In Sung, an out-of-luck university graduate who stumbles upon the haunted phone. Shocked by the discovery, In Sung is quickly persuaded by Sun Joo to help uncover the truth—especially after hearing about the massive reward Sun Joo is offering.

As In Sung steps into Sun Joo's shoes as the company's new "CEO," tensions rise, especially with the skeptical secretary, Jung Se Yeon. Now, working in the shadows, can they uncover the mystery behind Sun Joo’s death and bring the culprits to justice? The stakes couldn't be higher!
