Ralph is not like other mice. He is always looking for a new adventure. When a young guest arrives with a shiny miniature motorcycle, Ralph knows that it is his lucky day and takes it out for a spin. A Scottish lad has a tough decision to make. He will have to decide if he wants to be a Highlander like his father's people or a Lowlander like his mother's people. Maybe he will be able to combine his hunting and herding skills into something special....
