The Feldmarschallin neglected by her husband uses the morning exchanging caresses with her lover, the young count Oktavian. Since her cousin, Baron Ochs of Lerchenau bursts without any notice, in the Ante-Chamber of the marschallin in der Rosenkavalier. Just in time, Octavius manages to disguise himself as a Chambermaid. Ochs, who has come to make with Sophie Faninal, the daughter of a rich upstart, recommend a matchmaker for his wedding by the Marschallin, immediately takes a shine to the "Chambermaid". The Marschallin Octavian names him as the appropriate and shows him a Locket of her lover. Ochs is most puzzled about the "similarity" of the "Chambermaid" bearing the portrait of Oktavians, but accepted the proposal. When Octavian later occurs some time in the function of the Brautwerbers for Sophie, the two fall into each other. Ochs, who is only interested in the girl's dowry, is also still very coarse acting to her as Sophie is forced to sign the marriage, Octavian takes the sword and slightly injured him on the arm. This connection, which is wanted, to undermine, the father of Sophie and Ochs, Ochs will be made now a trap. In a letter, the "Chambermaid" to a get-together in a suburban Guest House invites him. There, Ochs, who accepts the offer of joy, and the Octavian dressed as maid meet again. When he wants to take "her" break various figures in the room and start a disguise. Last cause even Faninal, Sophie, a Police Commissioner, and the marschallin in der Rosenkavalier. Finally, Ochs must recognize that he has served as a groom. Octavian and Sophie are embarrassed with the marschallin in der Rosenkavalier. As the latter is the new tendency of Oktavians certainly, she leads him - quite the mistress of the scene - the younger Sophie and consigned his fate to the young couple.
