Country-club slacker Ensworth Harding is in for a surprise on his eighteenth birthday. "Son," his father tells him, "I give you a great gift today. See that open road? Your destiny lies down there." Ensworth is then given instructions to deliver a letter to an address in Savannah, Georgia, and warned, "If I hear so much as a peep until your journey is complete, I will disinherit you.".
