Max and friends travel to the site of the latest dinosaur appearance without bothering to check the atlas. Fortunately for them, as they transport themselves into the middle of the Pacific, they do somehow land on solid ground. As they track a Ceratasaurus across this mysterious island, they slowly come to realize that they’ve stumbled onto the top secret location of the Alpha Gang's secret headquarters. As if facing off with these villains over every new dinosaur weren't enough, now they must go head to head on the Alpha Gang's home field.
