On July 30, 1975, the most powerful and feared labor leader in American history stepped into a maroon Mercury in a Detroit parking lot and was never seen again. Jimmy Hoffa’s disappearance remains unsolved a half century later.

This episode goes beyond the mystery to examine how Hoffa built a national Teamsters empire through brutal tactics, mob alliances, and strategic genius, then lost control of it through hubris. It traces his journey from Depression-era streets to the pinnacle of power, his federal convictions, and the fatal comeback bid that put him on a collision course with his former underworld partners.
