It's the early days of the commercial internet, when downloading a badly pixelated soft core porn Gif took half an hour and would probably fail on 95% after you lost your modem connection. Former virus writer Dade (Johnny Lee Miller) (better known as Zero Cool or Crash Override - on LinkedIn no doubt) gets back into the hacking game and joins a gang of hackers (including a rather amazing looking Angelina Jolie) who are hacking into a system owned by computer expert Belford (Fisher Stevens) trying proving he is on the take. But as Belford prefers to be known as The Plague we can probably guess he is up to no good...
Computing in movies has always been problematic, especially so in this film. The graphics were dated even in the day, of course everyone "hacks" computers by typing really fast! I started my career in internet development when this film came out, to be honest it wasn't much like this. Which is a shame.
It is totally nonsense of course but fun.
