In a typical town, children are threatened with the legend of the fearsome Patalarga (Longleg). To the parents, it is nothing more than an advantageous invention so that children do not bother during nap time. However, Teto, Maru, and Ramón discover that Patalarga actually exists. Contrary to his appearance, it is a very lovable and kind creature, and they deeply bond with him. Together they will venture on the dangerous mission of freeing Patalarga from the intendant’s tyrant domain, in what will be the adventure of their lives. They will face alone an adult world that ignores them, a corrupt politician who has much to lose, and on the way they will leave their childhood behind.
