Rosa Baiana is a strong and courageous woman, the companion of Edmundo Lua Nova, who abandoned her with seven children to travel the world. Her children, Agenor, Ivan, Bráulio, Walter, Orestes, Cláudia, and Edinho, ended up connecting their lives to oil, working in the oil fields of Bahia, without, however, detaching themselves from their mother, the ultimate authority and final word in the family. Rosa imposes her personal worldview on everyone. The children don't dare contradict her, even when their lives conflict with their mother's standards. Until the day Edmundo Lua Nova returns home after twenty years away.
