Prehistoric fantasy animation. Pitt wants his tribe the Piteks to progress, but sadly his family and friends aren't as open to new ideas! Luckily Pitt can always rely on his pterodactyl friend Kantrop to help him try and advance the tribe. Pitt believes that his dad, Stef, should not be put in danger in front of ferocious beasts for a laugh. Sariac accepts Pitt's plea for more intelligent entertainment - if Pitt fails, Stef's banishment in the jungle will become permanent. But Pitt's first theatre rehearsals go from one disaster to the next. Can Pitt make Sariac laugh to save his dad?
