this is almost a remake of an HBO movie
in that movie, a group of computer programers who have just devolped some super computer security program that the cia wants to purchase. When they decline the cia's offer, they are not to thrilled...
the programers then take off for a weekend of paintball in a remote location, where a cia hit team has also been inserted into the area.
the rest of the movie plays out with the cia spooks hunting down the paintballers.
the movie is atleast 10 years old by now, as i remember seeing it back in late 90's.
it was actually pretty good. can't remember the name of it for the life of me though.
