Background
Some years ago Dr Falke and his friend Gabriel von Eisenstein were invited to a ball. Afterwards Eisenstein left Falke lying in a park, completely drunk and dressed as a bat. Falke had to walk home in his costume, an object of ridicule. He has been bent on revenge ever since.

Act I: The Eisensteins' home
The Eisensteins' domestic, Adele, has been invited by her sister Ida to Prince Orlofsky's ball. She searches for an excuse to get the evening off. That suits her employer, Rosalinde von Eisenstein, just fine – her former lover Alfred has just turned up. Eisenstein himself has to go to prison that evening for insulting an official. His lawyer Dr Blind has managed through sheer incompetence to get the sentence lengthened to eight days. Falke says he wants to "cheer up" Eisenstein and invites him to Orlofsky's ball. Once husband and wife have said goodbye to each other, Rosalinde lets Alfred in. They are surprised together by the prison director, Frank, who has come to arrest Eisenstein in person. Alfred is obliged to pretend he is Eisenstein to avoid attracting unwelcome attention.

Act II: Party at Prince Orlofsky's house
For Falke, the ball at Orlofsky's house is a chance to exact revenge with a "little dramatic joke". He has invited not only Eisenstein, but also Rosalinde, the housemaid and even the prison director. He plans to humiliate Eisenstein in front of everyone. Adele has come as an aspiring actress called Olga, Eisenstein as Marquis Renard and the prison director as Chevalier Chagrin. Falke announces a surprise guest, an ominous Hungarian countess – Rosalinde in disguise. Eisenstein tries to seduce the supposed countess. Rosalinde manages to get hold of Eisenstein's instantly recognizable repeating watch to serve as evidence. Eisenstein recounts with relish the story of the bat, alias Falke. There's drinking and merrymaking and Falke calls on everyone to drop all formality. Eisenstein almost manages a glimpse behind Rosalinde's mask, but then the clock summons him [and Frank] to prison.

Act III: In prison
The prison guard, Frosch, has some trouble dealing with the perpetually singing Eisenstein, alias Alfred, and with his own shortcomings. Frank, the prison director, feels the worse for all that partying. Adele and Ida come to see him, hoping for his patronage. Eisenstein has arrived to begin his prison sentence, but discovers that he's already behind bars. To find out what he can about the false Eisenstein, he decides to take the place of Dr Blind, who has just turned up as well. Rosalinde comes to warn Alfred. There are confrontations and various recognition scenes. The Eisensteins realize they came close to committing adultery the night before. They all agree: "Champagne was to blame!"
