Peter Capaldi explores the story of Scotland's art. He had a talent for drawing and a love for art that took him to art school in Glasgow, but soon after graduating he became an actor. Capaldi spends time with the paintings and the artists that have made Scottish art special. He sketches some of the most important Scottish portraits, and by focusing on the tradition of portraiture that goes back 500 years, Capaldi shows how Scotland's art has reflected the changing face of the nation.
