Watch on Soap2day. 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 a Midwestern landscape.
