Wildcat “Wildy” Jackson and her sister Jane arrive in Centavo City with big dreams of striking it rich in the oil business. Though Wildy has neither land nor know-how, she convinces Joe Dynamite, a crew foreman, to help her prospect. Joe doubts they'll ever find oil, but Wildy persists. After several adventures and a turbulent romance, Wildy and Joe ultimately prevail, and a gusher explodes over their triumphant finale. The score (the Broadway debut of Cy Coleman and Carolyn Leigh) includes the showstopper "Hey, Look Me Over."
