Solange and Carlos have been inseparable since childhood, a lifelong romance culminating in a lavish, highly anticipated society wedding in Rio de Janeiro. However, the dream fractures instantly on their wedding night. Confronted with Solange's nervous inexperience, an impatient and aggressive Carlos forces himself on her, committing a brutal marital rape. The trauma leaves Solange completely closed off to her husband, yet her suppressed desires manifest as a consuming obsession with anonymous sexuality. Seeking an escape from her stifling domestic reality, she begins boarding the city's crowded public buses, picking up random male strangers for intense, fleeting sexual encounters in cheap motels before returning home to her clueless husband. As Solange slips deeper into a double life, navigating the thin line between a submissive housewife and a fiercely liberated woman, the emotional distance between the newlyweds spirals toward an inevitable, explosive psychological breakdown.
