In the austere halls of a prestigious Midwestern university, the world of abstract mathematics collides with the quiet tremors of a family in mourning. The film opens on a campus where brilliance is measured in chalk‑dust equations and the lingering scent of old books, yet beneath the scholarly calm lies an undercurrent of emotional unease that seeps into every corridor.

​Catherine has spent years navigating the delicate balance between graduate studies and caring for her enigmatic father, a once‑revered mathematician whose mind was as brilliant as it was fragile. His genius, shadowed by years of mental instability, has left an ambiguous inheritance of both intellectual promise and personal doubt. As she confronts the loss of the man who both nurtured and haunted her, she finds herself wrestling with the question of how much of his extraordinary talent—and his turmoil—might be hers to bear.

Enter Hal, a former student of the late professor whose own ambitions drive him toward the same lofty heights that once defined his mentor. Their meeting sparks a tentative alliance, charged with both admiration and uncertainty, as they each seek a foothold in a field dominated by towering legacies. At the same time, Claire arrives from a more polished world, embodying the expectations of family duty and the practicalities of estate and career, creating a subtle rivalry that underscores the differing paths the sisters might take.

Against this backdrop of vaulted lecture rooms, quiet libraries, and the ever‑present hum of mathematical possibility, the story unfolds as a study of love, loss, and the haunting allure of genius. The tone shifts between introspective melancholy and the electric spark of intellectual curiosity, inviting the audience to wonder whether Catherine will step out of her father’s shadow, embrace her own brilliance, and find a way to reconcile the fragmented pieces of her family’s past.
