When high-profile spies around the world start vanishing without a trace, Katherine "Kat" Beckett, a seasoned spy for Interpol, is tasked with investigating. The trail leads her to a tech billionaire, Lucian Blackwood, who has developed a mind-control technology capable of rewriting the memories of entire populations. Kat must go undercover, infiltrate Blackwood's inner circle, and gather enough evidence before she becomes his next victim. The deeper she digs, the more she questions whether her mind has already been tampered with.
