The film presents the story of the “war of the currents” between electricity titans Thomas Edison, and partners George Westinghouse and Nikola Tesla, which determined whose electrical system would power the modern world. Edison has decided on Direct Current (DC) but it is limited in range and expensive. Westinghouse sets out to prove Alternating Current (AC) can work over longer distances at significantly lower cost. Edison and Westinghouse compete to get cities across the United States to use their system. Edison suggests that AC is dangerous and engages in a publicity war, while Westinghouse stands behind the technical merits of AC. As Edison struggles to find ways to make DC more affordable, Westinghouse attempts to get the high voltage AC system to work with motors.

The competing systems come to a head as they both put forward proposals to illuminate the Chicago World’s Fair.
