Due cuori fra le belve

An important Italian scientist disappears in the Jungle, and his niece Laura sets off to find him. Toto, dance teacher, ends up in the wrong steamer trip, and discovers that the companions of the niece have a sinister plan: kidnap her. The ship, however, is shipwrecked on the island of the Jungle, and Toto is worshiped as a god by the natives, and is then received by the dispersed scientist, who sees him as "the missing link in the evolutionary chain of mankind".
