Ageing Australian screenwriter Bob Cavanaugh flies into L.A. to sell his screenplay, The Mighty Kygor, to a major Hollywood studio. But his world comes crashing down when he's informed a similar script is in the works and his script is no longer needed. Devastated, he enlists a beautiful and street-smart B-movie actress who realizes his script will be the next Hollywood blockbuster and wants to play a part in his success. With her industry knowledge, Bob discovers his script has been plagiarized entirely as a new movie, and sets out in pursuit of those responsible to convince them to honor his deal.
