A young trumpeter rises through the jazz world and finds love.

Farmer Jabez Stone, about to lose his land, agrees to sell his soul to the devil, known as Mr. Scratch, who gives Jabez seven years to enjoy the fruits of his sale before he collects. Over that time, Jabez pays off his debts and helps many neighboring farmers, then becomes an advocate for the upstanding Sen. Daniel Webster. When Jabez's contract with Mr. Scratch concludes, he desperately turns to Webster to represent him in a trial for his soul.
