Set in the Oklahoma oil fields shortly before the outbreak of World War I, Oklahoma Crude is the story of Lena Doyle and her desperate fight to bring in her oil well against overwhelming odds. Outrageous, cantankerous, and stubborn, Lena lists all men as her enemies including Cleon, the father she hasn't seen in many years, and Mace, the part-time con-man, full-time drifter she hires on to protect her well against Pan-Okie, the giant combine threatening to drive her off her property.
