In the emerging industry of electricity there is no bigger prize than powering the world. The two leading minds of their time, Thomas Edison and Nikola Tesla, go to battle over how power should be transmitted across the globe. By the very nature of their inventions—Edison's long lasting bulb and Tesla's alternating current motor—each stakes out an opposite position on electric current. What begins as a working relationship between the two men turns into a million-dollar "War of the Currents" in which the grand prize is the right to power the 1893 World's Fair in Chicago. Before the winning bid is read, there will be a broken promise, a powerful alliance, and a bizarre public relations campaign with deadly consequences.
