The trailer for Denial opens as footage of a man denying the Holocaust rolls. Shortly after, we're taken to 1994 Atlanta, Georgia, where Professor Deborah Lipstadt (Rachel Weisz) delivers a speech in a lecture hall about who Holocaust deniers are and the "hidden agendas they won't admit to." When she pauses, a man named David Irving (Timothy Spall) stands and challenges Deborah. He's the same individual who appeared at the beginning of the trailer.
The trailer continues as we're informed that a lawsuit has been filed against Deborah by David, who claims his career and name have suffered real damage as a result of a book she wrote. Deborah puts on her armor as she prepares to battle David in court and his sharp claims that the Holocaust is a manufactured lie.
