Silicon Valley-based Pax AI Corporation is one of the hottest companies in artificial intelligence. One of their top scientists is murdered at a tech conference, and company executives and foreign spies are all suspects. In the aftermath of the killing, CIA officer Colt McShane has been assigned to a joint counterintelligence unit based in San Francisco. The unit's leadership believes that an espionage ring has been stealing technology from Pax, and they want Colt to use his past relationship with Pax executive Ava Klein to penetrate the company's inner circle, and uncover the mole.
