Revolution - Season 1 - Complete

Revolution takes place in a post-apocalyptic dystopian future. Fifteen years earlier, a new technology had been developed by the U.S. Department of Defense to disarm opponents in the battlefield. The technology was based around inert air-populated nano-machines which are capable of nullifying electricity and self-multiplying. The technology was pursued by the Department of Defense and weaponized, but after deployment, the nano-machines spread quickly out of control worldwide and effectively disabled all electricity on Earth within a single night, ranging from computers and electronics to car and jet engines. Trains and cars stopped where they were, ships went dead in the water and fly-by-wire aircraft fell from the sky and crashed.
People were forced to adapt to a world without electricity over the next fifteen years. Due to the collapse of government and public order, many areas are now ruled by warlords and militias.
The series starts with the surviving Matheson family: Ben, Charlie, and Danny, now living near what used to be Chicago, who possessed a pendant-shaped device (a USB flash drive contained in a pendant) that is the key to not only finding out what happened fifteen years ago, but also a possible way to reverse its effects. However, Sebastian Monroe, the General of the Monroe Militia and self-appointed President of the Monroe Republic, an area of the former United States east of the Mississippi River northward of Kentucky and the Carolinas, now possesses that power for himself seeking conquest of the entire former United States of America. The remaining Matheson family, joined initially by Miles Matheson, Aaron Pittman, and Nora Clayton now strive to counter the Monroe Militia. Monroe's new benefactor, Randall Flynn, a former U.S. Assistant Secretary of Defense who 15 years earlier ordered the deployment of the weaponized technology that caused the blackout, now seeks to fortify Monroe in his efforts after Rachel escaped from his custody.
