Filippo is a boy with Asperger's syndrome, a developmental disorder similar to autism. Stefano is a boy who apparently seems superficial and self-confident. He has just returned from the United States where he worked as a lawyer then it turns out that he was actually a barman in New York, due to the death of his mother. After reading the will of the latter, he is forced, in order to receive the inheritance, to foster his brother, who lives with his uncle Ghigo, the founding lawyer of the family firm and the maid Maritza. But to make this happen, it is necessary to pass an assessment by the young psychologist Bruna Marchionni, who first feels distrust of the young man, but then changes her mind.
