The opera has four main characters: the aristocratic Marschallin; her very young lover, Count Octavian Rofrano; her brutish cousin Baron Ochs; and Ochs' prospective fiancée, Sophie von Faninal, the daughter of a rich bourgeois. At the Marschallin's suggestion, Octavian acts as Ochs' "Rosenkavalier" by presenting a ceremonial silver rose to Sophie. However, the young people fall in love on the spot, and soon devise a comic intrigue to extricate Sophie from her engagement. They accomplish this with help from the Marschallin, who then yields Octavian to the younger woman. Though a comic opera, the work incorporates some weighty themes (particularly through the Marschallin's character arc), including infidelity, aging, sexual predation, and selflessness in love (or the lack thereof).
