An emotional drama exploring the fine line between genius and instability is playing through August 24 at By the Sea Productions in Morro Bay.
David Auburn’s play Proof, directed by Samvel Gottlieb, features Wren Hall as a woman who has spent years caring for her brilliant but mentally ill father, a renowned mathematician played by Tom Ammon. The arrival of her estranged sister, played by Kira Dobson, and one of her father’s former students, played by Charles Charm, forces long-buried questions to surface about love, trust, and family.
