Bigna is a brilliant, clinical 28-year-old tsunami scientist who thrives on absolute control, masking her intense, submissive erotic desires behind highly structured, anonymous hookups. Frank is a drifting 33-year-old bartender submerged in a haze of nightlife, drugs, and casual trysts, seeking validation through the affection of strangers. When a chance encounter binds them together in a raw, fiercely passionate physical relationship, their completely opposite worlds collide. Over the course of 99 months, the film chronicles their exhausting, magnetic connection as it evolves from casual encounters into a consuming obsession. Trying to escape their toxic cycle, Bigna moves toward a stable career and marries a dependable colleague, while Frank adapts to a quieter, domestic life. Yet, no matter how many years pass or what stable boundaries they erect, the gravitational pull between them remains unbroken—forcing both to choose between the safety of the lives they have built and the destructive, undeniable truth of their desire.
