Julia Lerner is one of the most powerful people in Silicon Valley and an icon to professional women across the country. She is the COO of Tangerine, one of America's biggest technology companies. She is also a Russian spy. Julia has been carefully groomed to reach the upper echelons of the company and use Tangerine's software to covertly funnel information back to Russia's largest intelligence agency.

Alice Lu works as a low-level analyst within Tangerine, having never quite managed to climb the corporate ladder. One afternoon, when performing a server check, Alice discovers some unusual activity and is burdened with two powerful but distressing suspicions: Tangerine's privacy settings aren't as rigorous as the company claims they are and the person abusing this loophole might be Julia Lerner herself. Now, she must decide what to do with this information - before Julia finds out she has it.
