Synopsis:
June Robbins stumbles upon an injured caveman in the jungle. The caveman has been shot, and June patches him up. June learns that the caveman has been terrorizing a nearby town, so she calls in the Challengers.

The Challs arrive and investigate, finding a scientist, Dr. Manning, missing. Manning was experimenting with ways to communicate with animals. The caveman could be the results of one of the experiments. The Challs track down and with June’s help catch the beast. June gives the beast an elixir to drink, transforming the caveman into Dr. Manning.
