With the help of the fearless warrior Quorra (Olivia Wilde), father and son embark on a life-or-death journey across a visually-stunning digital universe -- created by Kevin himself - which has become far more advanced with never-before-imagined vehicles, weapons, and landscapes and a ruthless villain who will stop at nothing to prevent their escape.
