(Taken from Wikipedia) Set in 1912 during the growth of American exceptionalism, the game has protagonist, former Pinkerton agent Booker DeWitt, sent to the floating air-city of Columbia to find a young woman, Elizabeth, who has been held captive there for most of her life. Though Booker rescues Elizabeth, the two are pursued by the city's warring factions: the nativist and elite Founders that strive to keep the city for pure Americans, and the Vox Populi, rebels representing the common people. Booker finds Elizabeth to be central to this conflict, and learns that she possesses strange powers to manipulate rifts in the space-time continuum that ravage Columbia.
