Charlotte Garside weighs less than 1.5 pounds at birth, small enough to fit on a credit card, and doctors diagnose her with a form of primordial dwarfism so rare they cannot fully classify it. The film follows her family as specialists debate whether she has MOPD type 1, which typically limits life to two or three years, or type 2, which can allow survival into the thirties. At two years old she stands 22 inches tall, small enough that her older sisters dress her in clothes made for their dolls, and the cameras catch the daily reality behind that detail: seizures, strokes, cysts on her liver, and a weakened immune system that slows but does not stop her learning. Only around 100 children worldwide share her condition, which makes Charlotte a case study for researchers still working out its causes and treatment. The film stays close to her household routines and her parents' conversations with the small group of specialists who study primordial dwarfism, tracking what her case teaches them as she grows.
