Plot:

Srinivasa Ramanujan (Dev Patel) is a self-taught mathematical prodigy living in Madras, India, with an extraordinary talent for discovering groundbreaking formulas. Despite his brilliance, he struggles to find stable employment due to his lack of formal education. After finally securing a clerical job at the Madras Port Trust, Ramanujan’s mathematical notebooks come to the attention of his supervisor, who recognizes his remarkable potential.

Encouraged to share his work with the world, Ramanujan writes to G. H. Hardy (Jeremy Irons), a renowned mathematician at the University of Cambridge. Impressed by Ramanujan’s genius, Hardy invites him to England to collaborate. Despite initial hesitation due to caste restrictions and his mother’s disapproval, Ramanujan decides to pursue his passion, leaving behind his young wife, Janaki.

Upon arriving in Cambridge, Ramanujan faces numerous challenges: cultural shock, racism, homesickness, and constant pressure to formalize his mathematical discoveries. Hardy, though supportive, demands proof and rigorous reasoning — a stark contrast to Ramanujan’s intuitive understanding of mathematics, which he believes is a gift from the divine.

As World War I rages across Europe, the environment in Cambridge becomes increasingly hostile. Ramanujan faces discrimination from students and faculty, limited food resources, and the emotional toll of being separated from his wife, who is unknowingly cut off from sending and receiving his letters due to family interference.

Despite his hardships, Ramanujan continues producing groundbreaking theorems at an astonishing pace. Hardy and Ramanujan develop a complex relationship rooted in mutual respect, intellectual friction, and deep admiration. Hardy pushes Ramanujan to prove his formulas formally, while Ramanujan inspires Hardy with his natural genius.

Ramanujan’s health begins to deteriorate due to tuberculosis and malnutrition, yet he remains dedicated to completing his work. His contributions eventually earn him election to the Royal Society — making him one of the youngest Fellows and the first Indian mathematician to receive the honor.

Realizing his declining health, Ramanujan returns to India, where he spends his final years continuing to write and explore mathematics until his untimely death at age 32. The film concludes with Hardy reflecting on Ramanujan’s extraordinary legacy and the lifelong impact their collaboration had on the world of mathematics.
