Chicago video producer, Ellie Foreman, has been absent from thriller author Libby Fischer Hellmann’s repertoire for almost a decade. Now she’s back…and soon entangled in a web of espionage, murder and suspicion that threatens to destroy what she holds most dear.

Hired to produce a candyfloss profile of Chicago-based aviation giant, Delcroft, Ellie is dismayed when company VP Charlotte Hollander, the architect of a new anti-drone system for Delcroft, trashes the production and cancels the project. Ellie believes Hollander was spooked by shots of a specific man in the video footage. But when Ellie arranges to meet the man to find out why, he’s killed by a subway train before they can talk. In the confusion, she finds a seemingly abandoned pack of cigarettes with a flash drive inside that belonged to the now dead man.

Ellie has the drive’s contents decrypted, but before long she discovers she’s under surveillance. Suspecting Delcroft and the ambitious Hollander are behind it, she’s unconvinced when Hollander tells her the dead man was a Chinese spy. Ellie and her boyfriend Luke try to find answers, but they don’t realize how far they ventured into the dangerous echelons of hidden power where more lives are on the line, including theirs.
