Luna and Sandro are two children aged 11 and 9 years respectively living in northern Spain, in a dysfunctional home where alcohol and drugs have always been present. The father abandons them, and the mother, a product of her addictions, is unable to care for them.

They are taken to a mountain region, in a coastal area of Andalusia. The finca of their maternal grandparents, whom they had never seen before, is located there. They are somewhat surprised by the very different landscape, and although there are chickens, goats and dogs on the farm, they lack the company of other children.

When they start at school – where because of their remoteness they have to be taken by car by Jesus the Deaf, a kind of adopted son for the grandparents – Sandro has serious behavior problems that seem to have no solution.

Then Sophie appears, the little windmill with colorful wings, who with her wise advice encourages things to be resolved, and that the lives of both change for the better.
