Outside Alliance, Nebraska, a whimsical monument rises from the desolate prairie. Fashioned from 38 spray-painted vintage automobiles stacked and buried upright, the structure known as Carhenge faithfully replicates its British counterpart, Stonehenge. CARHENGE: GENIUS OR JUNK? examines how this quirky monument challenged one community's definition of art, freedom of expression and appropriate land use. This humorous documentary charts sculptor Jim Reinders' efforts to save his creation from being dismantled. In addition, scholars, historians and artists provide insight into how this public art installation continues to beckon bemused visitors to this small Midwestern town each year.
