The trajectory of Marguerite's future, a brilliant mathematics PhD at France's prestigious Ecole Normale Supřieure, seems perfectly planned out. As the only woman in her class in the male-dominated field of mathematics, Marguerite nervously awaits the completion of her years of hard work at her upcoming thesis defense. However, on the crucial day, an unexpected mistake in Marguerite's theorem throws off these plans, triggering a personal crisis that unravels all her certainties and career aspirations. With her old life upended, she has to navigate the real world for the first time gaining fresh insights into life, meeting new friends, and exploring the possibility of romance. MARGUERITE₂S THEOREM is an unexpectedly tender and life-affirming portrait of one woman's journey to define life on her terms and find a balance between the rationality of the mind and the need for human connection.
