A young lawyer is determined to identify who is murdering members of a wealthy New York publishing family.

Unrepentant Tennessee moonshine runner Luke Doolin makes dangerous high-speed deliveries for his liquor-producing father, Vernon, but won't let his younger brother Robin join the family business. Under pressure from both out-of-town gangster Kogan, who wants a piece of the local action, and Treasury agent Barrett, who wants to destroy the moonshine business, Luke fights for his fast-fading way of life.
