'Proof' is a play about relationships -- Parent-child. Sisters. Lovers. A tender, witty, compassionate, and melancholy story, 'Proof' follows Catherine, a troubled young woman who has spent years caring for her brilliant, but unstable father, Robert. Released from her self induced obligations, she must now deal with the real world. Enter Hal, a former student and great admirer of her famous mathematician father. Enter Claire, her long absent sister who masks her own self doubts and worries with nagging good intentions. The character of insanity haunts and strains their relationships. A work of apparent importance is found in the pages of a notebook which raises the questions: A work of genius? Or madness?
