After being abandoned by her mother, Novali (Natalie Portman) spent her entire childhood in a trailer. Now, at the age of 17, she is about to become a mother. At such an important moment, her boyfriend Willy (Dylan Bruno) chose to abandon her. Novali, who was living on the streets, had nowhere to go and could only secretly board in a Walmart supermarket. As time passed, Novali gave birth to a baby girl in the supermarket, and she also turned into a local "celebrity". After becoming famous, Novali not only received 500 yuan in funding, but also got the opportunity to work at Walmart. At the same time, her mother, who had been away for many years, also found Novali, hoping to reconcile with her and spend the rest of her life together. Unfortunately, after running away with Novali's property, her mother disappeared again. Fortunately, with the help of a kind nun and an honest librarian Forney (James Frain), Novali and her child finally found a place to live.
