Benny's parents are splitting up. His mom leaves home after a fight about a mysterious splinter that is rumored to be part of an important relic. Benny's dad has always liked clutter, but now, he begins hoarding everything from pizza boxes to old motorcycle parts.

As his house grows more cluttered and his father grows more distant, Benny tries to sort out whether he can change anything at all. Meanwhile, a local teacher enters their quiet Missouri town in America's Most Charming Small Town contest, and the pressure is on to clean up the area, especially Benny's ramshackle of a house, before the out-of-town guests arrive.
