The Burger Fun Crew at store #6678 in Monteland, Michigan is experiencing one of the busiest and most profitable quarters in the store's history. The store is slammed with customers almost every weekend.
But, the store's workers have noticed a strange turn in the demeanor of their customer base. There seems to be some other force at work besides brand loyalty that's causing the boom in business. The workers find out what that is one weekend as they come under attack by the very customers they had served for so many years. Under invasion by rabid customers, the crew must fight their way out of the store if they are to survive.
What happens when fast food customers can't get enough?
