The Disappointment: Or, The Force of Credulity is a documentary about the search for four lost treasures buried on a single farm in Missouri. These treasures include a Spanish explorer's gold, silver from the Civil War, mysterious stone carvings, lost texts, and a wife's attempt to heal her husband and protect herself and her children. Part personal documentary and part historical essay, The Disappointment traces the patterns of cultural forgetting etched in the landscape of the Austin Farm.
