Spearheaded by Vito Genovese, more than 50 leaders of the organized crime syndicates from around the country converged on the sleepy town to discuss upcoming expansion plans. Their plans are foiled when local police trooper Ed Croswell discovers their activities and, consequently, exposes the mob to the American public. Croswell's actions shed light on the massive web of corruption and changed the face of law enforcement forever.
