A family of legendary explorers, the Clades, are known for their adventurous spirit and groundbreaking expeditions. Searcher Clade, the son of the renowned explorer Jaeger Clade, has settled into a quiet life of farming, having discovered a plant called Pando that provides a renewable source of energy, crucial for their community's survival. His own son, Ethan, however, has inherited the family's thirst for exploration and longs for adventure. The family dynamic is strained, with Searcher's pragmatic approach clashing with Ethan's adventurous spirit, and the lingering shadow of Jaeger's disappearance on a perilous quest years earlier.

The Clades' lives are upended when they are called upon to embark on a mission to investigate a mysterious and uncharted land that poses a threat to their world’s energy supply. Alongside their three-legged dog, Legend, and a skilled pilot named Meridian Clade—who also happens to be Searcher's wife—this intergenerational trio sets out on a new journey. They must navigate their familial relationships while facing an array of fantastical creatures and unforeseen challenges in an environment unlike anything they've encountered before. As they push forward into the unknown, the Clades uncover secrets that could alter their understanding of nature and their family's legacy.
