Gala, a 15-year-old teenager, has lived all her childhood with her best friend, Lluna, who has a mild degree of autism. Together they train in the same athletics team where, this year, for the first time, they have been assigned to separate groups. Gala will be forced to leave her comfort zone and join a group of girls who seem to have different interests from hers. From then on, Gala will start to deal with these two disparate worlds.
