His mother oddly still treats Antonio Dorigo, a fifty years old architect, as a child. Although in a relationship with Luisa, Antonio visits Ermelina’s house, where he has pleasurable encounters with twenty-years old Laide. The death of his mother pushes him to strengthen his relationship with the girl, although illegal, with a check. However Laide, who is very little interested in the money of her lover, accepts him as an “uncle” and continues her swindle with her frequent encounters with a friend, who she presents as a cousin, from Modena. Aware of the situation, although in bewilderment, Antonio tries to push Laide away and regain Luisa’s trust but ends up failing.
