Newlyweds Cora and Archie set out on their honeymoon to Los Angeles in 1926. A Londoner, Archie has a love for American films, especially if they include archeology, his specialty. Cora’s passions are adventure and jumping in with both feet. During a tour of a movie studio, Cora gets the harebrained idea for Archie to use his amateur acting skills to pretend he is a famous English actor in order to finagle an in-depth tour of the studio.

While touring an active movie set for a Western film, they witness an actor walk off the set, leaving the director in a bind. Archie overacts his persona, catching the ear of the director who then begs him to take the actor’s place. Their movie project, titled The Cowboy and the British Dandy, is perfect for Archie, and he starts immediately.

The lark turns into a problem when they return the next morning to find the star actor murdered. The police detective suspects everyone, including the newlyweds. With their magical sidekicks, Arve and Ola, they set out to find the real killer. Will Archie be able to resist the lure of his sexy young costar? Will Cora be able to stay out of trouble with her impulsive tendency to leap before she looks? And who are the mysterious apparitions that keep appearing out of nowhere?
