Addy and her parents have moved to a boarding house. There, Addy meets an inspiring friend, M'dear. Like many people who grew up enslaved, Addy doesn't know when she was born, so M'dear urges Addy to claim a day for her birthday. Then M'dear falls ill. When Addy goes out to get medicine, she faces prejudice - and danger. M'dear helps Addy overcome her anger and gives her a deeper understanding of freedom. When Addy finally claims a birthday, it is a special day indeed, and the whole city celebrates.
