The Teacher

When an FBI Agent's family is killed in a terrorist attack, her outrage to hunt down the people responsible is fueled by the discovery that this is just the first in a series of "lessons" and that brutal attacks will follow, with the intent of someone identifying themselves as "The Teacher", seeking to bring America to its knees, by not only causing horrific acts of terrorism, but also eroding the sense of freedom, which had been the very cornerstone of America's foundation, as a country.
