Catherine has devoted years of her life to her father Robert, a legendary mathematician whose brilliance is matched only by his instability. Now, standing at a crossroads she never anticipated, Catherine finds herself navigating a grief she can barely name, a sister who sees everything differently, and a young mathematician named Hal who has arrived with questions she isn’t sure she’s ready to answer. When a stunning discovery surfaces from within Robert’s private notebooks, everything Catherine thought she knew about herself, her father, and what she is capable of is suddenly, irreversibly in question.

Proof is a mystery of the mind and the heart. A play about genius, inheritance, and the terrifying vulnerability of allowing yourself to be known.
