The "friend" is interrupted in his assault by screenwriter Walter Thornton, who arrives in time to save her from an even more disgusting fate. Walter's rescue of Jerilee begins a friendship between the two, and before you know it, the two fall in love. They marry. Their marriage falls apart when Jerilee's script rewrites actually improve one of Walter's screenplays and he feels one-upped. Jerilee then goes through affair after sordid affair in her attempt to write her own screenplay and get it produced.
