It's hard to properly write and execute a good film when it's centered around only a few characters in one location and ATM is no different, in fact, it's pretty much what you'd expect it to be -- from the idiotic characters making many illogical decisions, to the killer having little-to-no motive for everything that transpired. As interesting as it managed to be, you'd have to really ignore all the holes in the script to enjoy this.

The "story" focuses on a few co-workers as they head home during the holidays, but make a quick stop at a nearby ATM first, so one of'em can get some cash and grab a bite to eat. Naturally it takes three people to withdraw from an ATM, so they all crowd around the machine and as they're about to leave they spot a large creeper in a coat standing in the distance between them and the parked car. Their fears of being robbed turn for the worst when they witness the mystery man violently murder a passerby, who was simply walking his dog. Now the trio are tripped within the confines of the ATM, while the coated man on the outside tries to flush them out.
