For more than twenty years, the band Anthrax has been called the underdogs of heavy metal. Now, after post September 11th events, Anthrax is not sure what to call themselves as their name has taken on a meaning they never imagined. This hour documentary follows the band from the birth of thrash metal; through the violence of moshing; into the fusion of metal with rap music; and arrives at a bio-terrorism scare called Anthrax that threatened to ruin the band. See how the heavy-hitting metal heads from New York have battled blows throughout their tumultuous career, and somehow managed to continue slugging.
