Sertão Sem Fim brings together the stories of three women from the community of Três Outeiros de Macaúbas: Maria Tertulina, her granddaughter Tertulina Alves and Maria Izabel, to create the "Poetic Myth" character Bastia.
The play tells the story of Bastia from her birth to her widowhood, an unmarried woman who started her family in Arraial de Via Crucis, where they work hard to cultivate the land during long periods of drought and, with great sacrifice, manage to acquire a herd of cattle. The couple's prosperity becomes the reason for the death of her husband, who is murdered by colonels. Affected by this crime, she sets out in search of justice rather than revenge.
