Fritz Steppke and his friends Lämmermeier and Pannecke fly to the moon in a steerable balloon. Mrs. Pusebach has also joined the adventurous traveling party. She considers flying to the moon less dangerous than losing sight of her Pannecke.

Only when he recognizes Frau Pusebach as the woman he tried to win over during his last escapade on Earth does he become more approachable and lead the guests into Frau Luna's state room.

She immediately falls in love with Steppke, but his thoughts are with his bride Mariechen, whom he left behind in Berlin. So they all decide to take a trip to Earth ...
