When Rosemary's "colored" school in Missouri is shut down because of the new desegregation laws in 1954, she must attend sixth grade with all of the white kids. Her best friend contracts polio before school starts, making Rosemary the only black kid in her class. To make matters worse, she is seated next to Grace, an awful girl from a racist family. However, the girls come to realize that as outcasts, they have more in common than they thought, and an unlikely friendship blossoms.
