You and your neighbor have been at odds for years over the state of his front yard. You can't stand how it looks and are convinced that he is a complete slob. Meanwhile, the neighbor believes that one of your kids is tearing up his yard. One day, in the middle of yet another argument, you both witness a gnome come out from behind a bush, rip up a piece of the lawn, shake his fist at both of you, and run away. After a little investigating, you learn that a small colony of grumpy gnomes is responsible for all of the damage, but no matter who you talk to or how much evidence you provide, no one believes your story. When you find your house covered in dirt one day, you decide enough is enough. Reluctantly, you and your neighbor put your differences aside and decide to track down the gnomes before they wreck your entire neighborhood.
