Back in Manhattan, the writer Jabez Stone is a loser: he is not able to promote his books, he resides in a lousy flat and he doesn't have success with women. When among his friends Julius Jenson sells his publication for US$ 190,000.00 to a editor, Jabez fells envy and promises to promote his soul to the devil for success and accidentally kills a female with his studying machine. The-devil seals that a contract together with Jabez and knocks on his door, fixes the situation. His superior books have reviews but become bestsellers. Jabez enhances. Has success with women, but has no time to get his pals. Jabez matches with the publisher Daniel Webster who offers him a chance to break the contract.
