The downside? We have to wait a year for this! Aaaa!
Here is the synopsis from iMDB:
Sam Flynn, the tech-savvy 27-year-old son of Kevin Flynn, looks into his father’s disappearance and finds himself pulled into the same world of fierce programs and gladiatorial games where his father has been living for 25 years. Along with Kevin’s loyal confidant, father and son embark on a life-and-death journey across a visually-stunning cyber universe that has become far more advanced and exceedingly dangerous.
And remember: Flynn Lives!
