There once was a supermarket in a small country town that was known for its friendly service and the staff were all real close. One night, a group of employees were asked to work an overnight shift to prepare for the large day ahead of them... Christmas Eve. Everything seemed fine until the power went out. The backup generator kicked in, supplying power to give the workers some light. But, without reason, a man made an attempt to break in, but found that there were several workers busying themselves with the tasks at hand. The man then found a new motive... kill them all. As they run for their lives, who will make it out... and who will be the next victim?
