Written, produced and directed by Goldberg, and produced and edited by Diana Robinson, the documentary visits four countries to speak first hand with victims, witnesses and anti-Semites. Interviewees include former US President Bill Clinton, former UK Prime Minister Tony Blair, Journalists Fareed Zakaria and George Will, and Professor Deborah Lipstadt. The film is narrated in part by Julianna Margulies.

"Viral: Antisemitism In Four Mutations" examines the mass shooting at the Tree of Life Synagogue in Pittsburgh and the rise of anti-semitism on the far right. In Hungary, it looks at how Prime Minister Viktor Orbán launched a massive campaign reminiscent of Nazi propaganda against Jewish billionaire George Soros.

In England, members of the traditionally anti-racist, far-left Labour party conflate Israel and Jews with antisemitic vitriol, causing tremendous pain for the Jewish community. And in France, the film illuminates the seemingly endless wave of violence against Jews by Islamists and radicals.

The increasing bigotry and, at times, violence within each of these four countries paints a terrifying portrait of how global hatred disseminates and harms.
