The Moonshine War

In 1929 Kentucky, a federal agent attempts to make some real money before the alcohol ban is lifted by setting his sights on the whiskey cache of an old army buddy, John "Son" Martin (Alan Alda), who owns and operates a profitable still making moonshine whiskey. When Son refuses to cooperate with Agent Frank Long (Patrick McGoohan) over the profits, Long calls in the ruthless Dr. Emmett Taulbee (Richard Widmark), who uses violence to get what he wants.
