Proof

The acutely intelligent daughter of a deceased genius mathematician brings to light the truth behind a mysterious mathematical proof her father may have left behind. Before that, however, she must confront her rocky relationship with her estranged sister and nurture the nascent bond with her father’s ambitious young student. PROOF swept the Pulitzer Prize for Drama, the Drama Desk Award and the Tony Award for Best Play in 2001 when it first appeared on Broadway.
