SELENKAY follows 16-year-old Sofía (Gina Mastronicola), who's tired of always moving to support her globe-trotting scientist parents' careers. Her newest move takes Sofía and her siblings Lupo (Julián Caballero) and Flox (Luisina Arito) to Selenkay National Park. Sofía is thrilled at the prospect of finally attending a nearby "normal" high school, but her sense of normalcy is quickly shattered. She meets the mysterious Fénix brothers, who seem like they're up to no good. Despite the brothers' foreboding personas, Sofía can't keep herself from falling in love with Gael Fénix (Manuel Ramos). When Sofía and her new best friend Diana (Thais Rippel) get trapped in a magical fire, Sofía discovers that she has supernatural powers, and can produce water with her hands. Sofía learns that others have supernatural fire powers, and that she and her family are in danger. She must confront her magical origin story, fight fire with water, and navigate a teenage crush to protect herself and her family.
