A young woman grapples with the legacy of her father, a brilliant mathematician who revolutionized the field but whose mind deteriorated due to mental illness, leading to his untimely death. Struggling with her own volatile emotions and the fear that she may have inherited her father's madness along with his mathematical genius, she is left to piece together her identity and future while living in the shadow of his achievements. Her life takes a complicated turn when a groundbreaking proof is discovered among her father's numerous notebooks, raising questions about the authorship and the authenticity of the work.

Complicating matters further, the arrival of her estranged sister and one of her father's former students brings tensions to the surface. The sister, concerned more with settling their father’s affairs than understanding the depth of their loss, clashes with her. Meanwhile, the student seeks to understand the truth behind the proof, believing it could be the key to unlocking new mathematical ideas, but his intentions may not be purely academic. Between the intellectual challenge and the emotional turmoil, the protagonist must navigate a thorny path of doubt, legacy, and self-discovery, trying to prove not just the authenticity of the mathematical proof, but also her own worth and capabilities amidst the towering legacy of her father's genius.
