Their aunt and uncle in Texas send for them. After arriving, Edward accepts a job on a ranch. Big sister Anna thinks being a cowboy is too dangerous for her precious little brother, so she rides out to demand he not be allowed to work there. Instead, she's offered the job of cook. Since she'll be close at hand, she keeps her peace about Edward.
She settles in to her new job. Soon the rest of the hands, including the ranchers handsome son, arrive back from the cattle drive.
