Although Dick (Richard Talmadge) and Dorothy (Lucille Lund) emerge unscathed from the explosion, they find themselves seemingly trapped in a cave. Brasset's men, meanwhile, commandeer the remaining expedition, including Brasset (Walter Miller) himself, back to the hut. Having found a way out of the cave, Dick and Dorothy manage to free their captured friends and are soon on the trail of the gang. A vicious battle ends in a swamp filled with ferocious crocodiles.
