We soon discover that these are computer programmers, playing paintball against a rival company. We also find out that they pretty much suck, as the rival company lays them low from hidden positions. It seems Cleary used to work for the rival Gordon, and is still pissed that Gordon sold Cleary's under-contract work to the Feds, so Cleary uncharacteristically agrees to the next paintball game to even some scores. On the way to the playing field, three hours out of Chicago, their car breaks down on a secluded stretch. And then people start dying.
Unseen snipers start taking out players.
There's guilt on Cleary's part as his employees are picked off, there's something of a reconciliation between Cleary and Gordon, and there are more improbabilities than a winning streak in Vegas. Unfortunately, that scene actually started my brain working, and once that starts no plot point is safe. And just to make sure that we don't come up deficient with ridiculous plot devices, Cleary manages to reprogram one of the Infinity devices by poking at the circuit board itself. All I can say is, it was probably a good idea to make this one in Canada. Most likely created under the influence of Mountain Dew , Nectar of the Gods.
