Twelve-year-old Sumiko lives on a flower farm in California, and dreams of owning a flower shop someday. She is the only Japanese-American girl in her class, and is often the victim of bigotry, but she feels tranquil when she is among the flowers. Then the Japanese bomb Pearl Harbor and the United States government send all Japanese people to internment camps. Sumiko and her family are sent to an Indian reservation in the Arizona desert where she discovers that the Indians resent them for taking over their land. Living conditions are poor and Sumiko no longer has the flowers to comfort her, but helping Mr. Moto, a lonely old man, plant a garden, and developing a friendship with Frank, a young Mohave boy, leads her on a journey of self-discovery and helps her realize the real reason that her grandfather left Japan for America long before she was born.
