Robin receives his own Batplane for his birthday. Together he and Batman take a test flight and find a small island. Robin lands the plane after sighting a dinosaur on the island.

On the island, the Dynamic Duo encounter several people, dinosaurs, and a fake-sabertooth tiger. Everyone seems out to get them, until Robin finally exposes director Guy Markham. The island is a movie set and when Batman arrived they began filming his exploits.
