This documentary explores how two of the most powerful companies in the world – Coca Cola and Pepsi – have used advertising campaigns, publicity stunts, and other cut-throat tactics in an incalculably expensive bid to each be the top purveyor of beverages to consumers. It is a story that speaks volumes about who we are as a people, shedding an illuminating—and not always flattering—light on why and how we make the decisions we do.
