Newlyweds, Cora, and Archie set out on their honeymoon to Los Angeles in 1926. Londoner, Archie, has a love for American films, especially if they include any bouts of history relating to archeology, his specialty. Cora's passions include anything involving adventures 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 to finagle an in-depth tour of the studio.

Touring an active movie set, filming 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 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 as they return the next morning to find a man 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 co-star? 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?
