Chester Royde, an American millionaire, travels to Scotland with his new bride Carrie and sister Myrtle, to find out more about Carrie's Scottish ancestry. Their new 'relatives' turn out to be a little more authentically Scottish than they bargained for. Ben Nevis, Laird of Glenbogle Castle, is fiercely protective of his lands and the Macdonald clan spirit, but being cash-strapped he's not above attempts to marry heiress Myrtle to one of his many brawny sons. But then a group of hikers stumble onto his moor and spoil a day's hunting, sparking all-out war between gentry and commoners.
