Alfredino has a very rare disease that has forced him, since he was a child, in a wheelchair. Unlike his peers, he has never had the opportunity to discover the beauty and intensity of sex, forcing him to withdraw more and more in himself and to face suffering that is sometimes too great. After countless and useless attempts, the desperate family turns to a distant psychologist aunt. Alfredino initially refuses his aunt's attempts to help, but when she discovers his nephew's morbid and unspoken passion for pornography, that's it! The aunt will focus on this weakness of her, trying to win the trust and attention of Alfredino by showing more and more her body and becoming the erotic desire of her nephew. Hence a succession of events that will upset the family and its delicate relationships.
