In the movie White House Down (2013), we know that a bomb is on its way to blow up the White House. During this time, in one agency, they call an opposing operative via laptop.
One woman said that she would be able to convince or get answers out of the terrorism operator by calling them on the laptop computer, but she turns suddenly against the agency and yells all this stuff so the operative could hear.
She was with the agency all along until then. Some agents grabbed her and pulled her away into a room (or rooms) with glass covering.
Why did she turn on the agency like that when she was an agent in the first place?
