Proof

After spending years taking care of her mathematically brilliant, but unstable father alone, Catherine must face the invasion of the outside world when he dies. Her estranged sister Claire, who believes that everything can be fixed by Catherine leaving their childhood home in Chicago to join Claire in New York, and one of her father’s former graduate students Hal, who is looking for a trace of clarity in the nonsense filled notebooks that her father left behind, force her to confront the question that haunts her: how much of her father’s brilliance does she possess and how much of his instability will she inherit? Filled with biting humor, romance, and suspense, Proof is ultimately a play about our relationships with the people we love.
