A bomb placed by terrorists detonates under the Woodrow Wilson bridge near Washington D.C., killing hundreds of motorists. Days later, another bomb is found in a terminal at Baltimore-Washington Thurgood Marshall International Airport. Then a suspicious briefcase filled with a mysterious white powder is found in thetrunk of an abandoned car just yards from M & T Bank Stadium, home of the Baltimore Ravens.

Sixty members of the Maryland National Guard Reaction Force called up by Gov. Martin O?Malley rush to downtown Baltimore, cordoning off parking lots and setting up road blocks. Then two specially equipped Guards, part of elite haz-mat team, carefully inspect the briefcase.
