While on a vacation in England, Caitlin O'Connor finds an antique journal. Soon after she returns to the States, she adapts the journal's handwritten notes into a movie script and submits it to Piermont Studios. The studio gives the work a green light and she is hired and now pursues her dream as a screenwriter. Piermont decides to cover the movie studio and hires an investigator to trace the journal's history. After a shocking turn of events, the journal is revealed to be over a hundred years old, and it is believed that it was indeed written by none other than the fictionalized detective Sherlock Holmes's friend and assistant, Dr. John Watson. The enigmatic Arthur Kensington is the movie's new producer. Kensington believes the yellow-tinged leather book is a link to a hidden past that reveals a century old crime. Tony Langdon is the Piermont security detective in charge of investigating the journal's origin. Although, at first a skeptic, he becomes absorbed with his own analysis and his need to know the truth. After the movie wraps, the actors, crew, and other involved individuals begin to believe in Caitlin's mysterious journal. As truths are unveiled, it seems the so called fictional Watson, and the mysterious tale is genuine and tied to a dangerous and cryptic cover up in the distant past.
