Season 4 Episode 4
Toni Collette stars as Ellen Sanders, a top surgeon in Washington DC, has been tapped to operate on the President of the United States ... and then kill him. When masked men invade the Sanders home the night before the operation and take Ellen, her husband and two children hostage, Ellen's calm is rocked to the core. As tensions mount and Ellen fights for time before suiting up for surgery it becomes clear that the outwardly idyllic Sanders family isn't as perfect as originally thought. Nor are their captors as evil as one might suspect.
