Plot synopsis: Documentary telling the story of Balmoral, the royal family's most private residence. For over 150 years this Scottish castle has been home to royal traditions of picnics, stag hunting and kilts. From prime ministers to Princess Diana, life at this tartan-bound holiday home has not appealed to everyone. But there is another story of Balmoral, of how the royal family has played a role in shaping modern Scotland and how Scotland has shaped the royal family. Queen Victoria's adoption of Highland symbols, from tartan to bagpipes, helped create a new image for Scotland. Her values, too, helped strengthen the union between Scotland and England. Ever since, Balmoral has been a place that reflects the very essence of the royal family.
