Based on the book History on Trial: My Day in Court with a Holocaust Denier, this riveting, true-life drama recounts the courtroom showdown between historian Deborah E. Lipstadt and notorious Holocaust denier David Irving, who accused her of libel when she declared him a Holocaust denier. In the English legal system, in cases of libel, the burden of proof is on the defendant, therefore it was up to Lipstadt and her legal team to prove that the Holocaust had occurred.
