An archaeologist finds evidence that men and dinosaurs existed together at one point, but his discovery is considered fake by the Gotham Museum. In order to learn the truth of the mystery, Batman and Robin ask their friend Carter Nichols to send them back in time to the pre-historic era, where they find a hero by the name of Tiger-Man. The Dynamic Duo help Tiger-Man confront the villain called Borr, who keeps a frozen dinosaur in his cave hideout and threatens the nearby tribemen with its release if they don't comply with his wishes. During the confrontation, the ice that contains the beast begins to thaw and soon, the dinosaur is free to roam among men. The dinosaur does not live long in the environment of the Stone Age, but served its purpose by driving out Borr and his men. Tiger-man pledges to recreate the entire story on stone, thus giving an explanation for the archaeologist's discovery.
