Four profiles of professional deceivers, each built from interviews and archival material tracing how the con actually worked. Matthew Cox, a Florida mortgage broker, describes falsifying property documents to borrow against homes valued at five times their real worth before landing on the Secret Service's most-wanted list. Christophe Rocancourt explains how he talked his way into Hollywood and Wall Street circles by claiming to be a French nobleman, a Rockefeller heir, and a Russian prince. Jan Lewan, the Pennsylvania polka bandleader whose Ponzi scheme later became the Netflix film Polka King, walks through how he kept investors paying into a business that was already collapsing. Shaun Greenhalgh, the British forger, recounts producing fake Roman and Chinese antiquities, medieval relics, and nineteenth-century paintings convincing enough to pass through major museums and auction houses undetected for close to two decades. Across the four episodes the series stays less interested in the money than in the psychology, what made marks believe and what made each man capable of the lie.
