The Untouchables - Season 2 Episode 25 Mr. Moon

Autumn 1934. An armored truck, loaded with the special paper used in printing U.S. currency, is headed for the Bureau of Engraving in Washington, D.C. The truck is hijacked, and the 3 armed guards are tommy-gunned. Since counterfeiting will be on a national level, it's a federal offense, and so Eliot Ness and 5 other federal agents from around the country convene in Washington, D.C., and are briefed on the situation.
