Comments: A Congressman is investigating the private company that runs the Department of Homeland Security. The lead researcher for the Congressman is mysteriously killed in the Washington DC subway. A reporter from the Washington Globe (i.e. the Washington Post) finds himself unwillingly involved because the Congressman is an old friend. This helps to uncover a minor plot.
To play the Congressman they should have chosen someone who could lie more or, at least, could play a "redneck" politician: Ben Afleck is just too blue-blooded. Otherwise, this is a good thriller. It's based on a BBC mini-series.
