In the opening scene of JOURNEY TO THE CENTER OF THE EARTH, Jules Verne writes instructions to his descendants. Verne tells his future family how to access portals to secret dimensions, but tells them they must not enter the portals unless there's an Earthly imbalance. Fast forward to modern life, and adventurer grandmother Pola has detected that Earth's magnetic field is fluctuating rapidly. Pola decides it's time to enter a portal, but drops her grandchildren off at summer camp first. Her grandchildren and their friends are very excited to attend "Pompilio Camp," a camp led by famous adventurer Pompilio Calderón. The kids quickly realize that Grandma Pola has disappeared into a portal near camp, and they decide to rescue her. Once they enter this new dimension, the kids learn that they have to protect their family's secret from their villainous camp director, his robot henchman bird Claudio, and their ulterior motives.
