Caterina is a nun and has taken provisional vows for a month when she goes to a park when she meets a man who has found an abandoned baby boy and entrusts him to take him to the hospital. After doing so, Caterina begins to visit the little one and becomes attached to him so much that he tries to trace his mother through the sweater in which he was wrapped. This goes as far as Ernesto, forty-one, owner of a laundry left to him with his father's debts. Ernesto is unhappy with life and is all centered on his problems so as not to even remember the names of his collaborators. The boy's mother is perhaps Teresa, his former employee and Ernesto is perhaps the father. Thus began a crisis for Catherine as a nun and for Ernesto the awareness of not being the only unfortunate man on earth.
