The sun is hot, and tension is brewing in the jungle. The animals are seething with envy whilst watching the adorable Charlie the Chimp up to his antics swinging through the trees. Charlie seems to be good at everything he does. At the suggestion of the giraffe, the animals decide to challenge Charlie to a race across the wide, rolling river nearby, a feat which they all believe he won't be able to do. Will Charlie be left humiliated and demoralised? A huge problem lies before him; can he take on the challenge, face his fears and outsmart the jungle animals who all want him to fail?
