This film tells the story of Mel Mermelstein, a Jewish survivor of the Nazi Holocaust who was angered and horrified at the gall of the Institute for Historical Review, a neo nazi organization dedicated to claiming the Holocaust never happened. Although itching to challenge them, he is initially disuaded by the fact that the organization's standard tactic is to post a reward to anyone who can prove the Holocaust's occurance, then ignore all petitioners and claim that no one has presented any proof, thus ensuring themselves publicity and credibility. That reluctance is removed when a friend notes that this kind of lying represents a breach of contract, leaving the organization open to a lawsuit. Using this bold legal strategy, Mermelstein presents his proof, the IHR takes the bait and Mermelstein takes them to court.
