Like all other fairy tales, this one begins with: Once upon a time. Once upon a time, there were two friends, one was an actor in Copenhagen, the other in Oslo. The one in Copenhagen was called Osvald, and one day he was very angry. He stood in front of his director and told him what he thought of him in general and the tasks he was given at his theater in particular. So Osvald left. By a twist of fate, something similar happened in Oslo. Einar felt that his director did not take him into consideration, so he also left. Now the two meet in Copenhagen, and they experience an adventurous evening together, spiced with several well-known revue numbers.
