The rights to the book were purchased at great expense by Republic Pictures as a starring vehicle for B movie actress Vera Hrubá Ralston, who was married to the head of studio.
In the National Review in 1996, journalist Florence King described Jubilee Trail as a "good girl/bad girl western in which the male characters are all satellites".
The plan is that Garnet will travel to California with Oliver while he closes up his business out west and they both will return to New York the following year.
Oliver takes her to a dance hall called the Flower Garden, something Garnet would never have been allowed to do back in New York.
In the Flower Garden, a blonde actress named Juliette La Tour stops the show with her talent for stage presence and performance.
On the trail to California, Garnet and Florinda endure harsh temperatures, lack of water, and other such hardships with stoicism and bravery.
The train finally arrives in California with much rejoicing, although Florinda quickly succumbs to exhaustion brought on by the trail.
The letter reveals that before leaving California last year, Oliver had a tryst with the daughter of a wealthy native Californian and the girl gave birth to a son.
Charles was delighted at the opportunity to gain control of the property and expected Oliver to marry the girl on his return.
By the end of the story gold has been discovered on Sutter's Mill and John and Garnet fall in love and are married.
