The year is 1968 – one of the most turbulent in 20th century America. The three television networks are competing for supremacy of the airwaves in the run up to the presidential election. Lagging a distant third, ABC takes an audacious punt, and schedules a series of head to head debates during the Republican and Democratic conventions. Duking it out were two heavyweight thinkers - the rightwing William F. Buckley Jr and the liberal Gore Vidal. Buckley saw Vidal as a moral degenerative; Vidal considered Buckley's views to be dangerously anti-democratic. Both recognized the power of television in the changing media landscape, and soon a nation was transfixed. Robert Gordon and Academy award-winning director Morgan Neville bring an abundance of fantastic archive, and interviews with cultural commentators – including the late great Christopher Hitchens – to tell the story of a famously acidic rivalry which would endure for decades.
