In Episode 1 (the first book) Evan passes through a unique time warp wormhole that throws him back to 1946 Hollywood during the making of the movie “It's a Wonderful Life”.
After a period of extreme confusion as to how he went back in history, he ends up becoming friends with the film’s star, Jimmy Stewart, which leads to him working on the film as an assistant editor for Frank Capra.
Through this association, Evan helps save the film from getting bastardized by a greedy studio mogul and ensures that this timeless classic is made as it should be -- the movie we have come to know and love for over 70 years.
Evan meets a fellow time traveler, Dr. William Cooper aka- Coop, age 29, a brilliant scientist and time traveler who worked for Nikola Tesla and accidentally was propelled into 1946.
Coop recognizes Evan as a "fellow traveler" and gives Evan insight into how to navigate 1946.
Evan learns that he has been chosen to do what he did on his first journey and those in the future.
Evan senses that the "unseen hands" of destiny have decided that his missions are somehow related to a) Hollywood; and b) iconic films, movie stars and events germane to Hollywood history. Coop feels he is trapped - but sees in Evan a chance to escape 1946.
He becomes Evan's companion and together, they make a formidable team in their adventures through time.
