When a mysterious leather case begins to vibrate in Grandpa Nicolás's office, Leo and Mia discover a magical map that transports them to the Valley of the Lost Echo - a hidden world where dinosaurs still roam... and something mechanical is threatening their survival.
With the help of Mist, a brave little Microraptor, the siblings must solve riddles, follow glowing map clues, and outsmart a malfunctioning robot before the balance of this prehistoric world is destroyed forever.
But the adventure doesn't end when the story does...
