Beyond the World Beneath takes a further examination of a Missouri cave with evidence of prehistoric activity. As a follow-up to Footsteps into the World Beneath, the sequel explores never before seen footage of prehistoric impressions on muddy ledges and lower passages along with analysis of crude images by use of a portable x-ray fluorescence unit. There are also interviews from archaeologists regarding the finds made in the cave since the entrance collapsed. The film ends with analysis of raw footage by a fourth grade class taught by Dr. Samantha Miller Anth. The film is sponsored by the Missouri Humanities Council and produced by Cave Archaeology Investigation Research Network in partner with Triptone Productions.
