Legacy playwright Athol Fugard has made a home at Signature since being the inaugural Residency One playwright at the Center, and his South African-set stories, with themes of complex identities, racial tension, and social protest, remain as relevant as ever. In this new production of the “prophetic and brilliant” (The New York Times) Boesman and Lena, the human need for kindness, hope and compassion is on display in the struggles of abusive Boesman and his long-suffering wife Lena, who encounter a stranger while wandering the South African wastelands.
