Beginning with a hot summer trip in the middle of the city, Natsu hosts her sister and young niece, the latter who refuses to talk but spills her heart out about the fears of puberty onto the pages of her journal. Ten years later and in another sweltering summer, Natsu begins a rocky path towards motherhood as her fears of growing older and lonelier mirror that of her niece's past. Her journey reveals the complications that stand in the way of a single woman desiring a life that does not depend on the conventional company of men, especially in a world so ready to dispose of women at a certain age.
