Paige O'Toole only has a few memories of her mother, who left her when she was five, one of the most vivid being painting winged horses on the ceiling of her childhood home.
After she grows up, marries Nicholas and gets pregnant, she starts to doubt her own maternal love and ability, based on her history and lack of maternal care as a child. After their son Max slips off the couch and gets a nosebleed, she, questioning her own competence as a mother, flees and goes on a journey of self-discovery.
Paige revisits her childhood home in Chicago and tracks down her mother, now teaching children how to ride horses. She understands more about her childhood and her mother, and returns to her husband and child.
