Revolution takes place in a post-apocalyptic dystopian future. Fifteen years earlier, an unknown phenomenon disabled all technology dependent on electricity on the planet, ranging from computers and electronics to car engines, jet engines, and batteries. People were forced to adapt to a world without functioning technology. Due to the collapse of government and public order, many areas are ruled by warlords and militias. The series focuses on the Matheson family, who possess a special device (resembling a flash drive) that is the key to not only finding out what happened fifteen years ago, but also a possible way to reverse its effects. However, they must elude Sebastian Monroe the General and President of the Monroe Militia who wants to possess that power for himself.
