The story concerns a young prince named George. However, he does not enjoy his princely duties and does not love the princess to whom he is betrothed, so he and his friend sneak out to London for some fun ("Londonban, hej"). He uses a pseudonym, Bob. In London, he meets the pretty Annie, a poor girl. She does not know that he is the prince in disguise. The story is about how George becomes king, and the romances between George and Annie and between his betrothed princess and a soldier.
