Harald, the crown prince, is fresh out of military school and needs to restore his good name; King Olav presents him with various princesses and there are rumours of an impending marriage; Harald seems to be more interested in a common girl.

While Harald studies at Oxford, King Olav, grieving Crown Princess Märtha, hosts a birthday party filled with princesses; Harald longs for Sonja and his friends.
