Twenty-six year old Valeria is a reserved and lonely girl. She lives in Turin, where she works as an interpreter. She has no romance in her life outside of an unconscious attention to Massimo, a neighbour of hers, in his forties, whom she watches through the windows of her apartment. They have some chance meetings, but the man is still a stranger to her. When he moves to Rome, Valeria’s life seems to collapse. Following an impulse, she decides to leave Turin and follow him. Soon after, Valeria learns of the existence of Flavia, Massimo’s girlfriend. An accident, caused by Valeria herself, brings the two women together. For Flavia, Valeria becomes a valuable help in writing her novel on her husband, who died a few years before. For Valeria, Flavia is now the only tie to her former neighbour. The image of Massimo and Flavia as a perfect couple will soon prove to be a disappointing reality. Flavia, so sure of herself, will soon reveal her vulnerabilty when she faces the decision Massimo asks of her. This doesn’t stop Massimo from pursuing his romantic dream, when he at last turns his attention to Valeria.
