Roy Cohn personified the dark arts of 20th-century American politics, turning empty vessels into dangerous demagogues. Where's My Roy Cohn? unearths the origins of the seditious right wing's ascent, revealing how a deeply troubled master manipulator shaped our current political world. This shocking film exposes Cohn's malign influence and contextualizes him as a modern Machiavelli, tracing his rise to national prominence first as prosecutor of the Rosenbergs, then as handmaiden to Joseph McCarthy. After these twin disgraces, Cohn re-emerges as a New York power broker, mafia consigliere, white-collar criminal, and, eventually, the mentor of Trump.
