Basically, an escaped convict is trying to get his girlfriend to rehab and on the way kidnaps a happy couple. They end up trapped in a gas station while trying to survive an attack by some crazy fungus that consumes and controls what ever person or animal it gets into.
Nothing amazingly unique about it, but it's still a pretty good movie. Where a lot of low budget movies fail is in trying to do too much with too little. Splinter doesn't have that problem. It's essentially one set, a gas station and there aren't a lot of crazy computer effects in it.
