Open season in Oregon as Cotton Drennan, cowhanding on Jackson Malloy's ranch, wonders over the omnipresence of a crew of gunmen, the killing of a man and his wife, and aligns himself with homesteader Flagg and his daughter, June, whom Malloy is attempting to oust. With Malloy's decision to sell out to railroad magnate Abernathy, Cotton is on to Abernathy's imposture, avoids a frame when Malloy is killed, and returns to clean sweep the range. Superior.
