Two young siblings, Carmen and Juni, live an apparently normal life, unaware that their parents, Gregorio and Ingrid, are retired spies. After years of adventure, their parents have settled down to raise a family, keeping their espionage-filled past well hidden. However, old habits die hard, and when they receive a distress signal from their friend and former spy colleague, they feel compelled to help. Under the guise of a long-awaited family trip, they set off to answer the call for aid, only for things to go awry. With the adventurous couple kidnapped by the wicked Fegan Floop, it falls to their children to embark on a daring rescue mission.

Carmen and Juni discover a world of gadgets, gizmos, and their parents' secret safe house, revealing the truth about their family legacy. With no previous training but armed with an array of spy technology and their inherent cleverness, they decide to step into the world of espionage. Navigating through a series of dangerous and fantastical obstacles, including a virtual room of deadly foils and the discovery of Floop's castle that holds a collection of mutated secret agents, the children come to understand that the fate of their parents—and perhaps the world—rests in their small hands. As they delve deeper into this perilous new world, the pair realize that success hinges on their ability to work together as a family and trust in each other's skills.
