Sandra, who is 30, is about to marry Marco, a precise, rational 40 year-old specialist in orthopaedics. Then, at a basketball game, she meets Marco's younger brother Alex, a handsome, highly charismatic 19 year-old who is the leader of their s,all-town basketball team. It is love at first sight between the two, but that very night, while Sandra and Alex are driving home together, they have a tragic accident. Marco and Sandra's wedding is postponed, and three lead characters are forced to spend the entire summer holed up in an apartment, where the pain and the tension of the love interest between them transform their relations. A subtle erotic undercurrent is present throughout the film, finding its outlet only at the conclusion.
