Sarah's curly blonde hair isn't the only thing that sets her apart from her Amish community. Twenty-eight and single, Sarah doesn't believe a woman needs to be married in order to be happy. Her terminally ill best friend disagrees, however, and wants Sarah to promise to marry her husband after she dies. Sarah half-heartedly agrees only to make her friend happy. Her friend's husband, Samuel, has made the same agreement with no intention of following through.
Her friend dies and Samuel desperately needs help raising the children. Sarah decides to spend her days helping with the family and taking care of the chores while Samuel is away at work. She then leaves before nightfall. The odd arrangement soon raises eyebrows around the conservative Amish community. Shamed, Sarah must decide on whether or not to turn her back on the family and Samuel, a man she has started to fall in love with.
