Johnny Reason notices a woman with a long red braid swaying in the middle of her back as she steps from the train before him in St. Joseph, Missouri, where his life as a Pony Express Rider will begin. But as he settles into his new life, Erin, a bold young woman seeking a husband, sets her sights on him. He soon wonders which is more dangerous -- riding for the Pony Express or being pursued by Erin Byrne.
And why do thoughts of the young lady with the long red braid continue to invade his mind?
Since her mother's death, Maggie Carter has struggled to get out from under her oldest sister's thumb to live her own life. Sparks of romance stir within her from the first moment she sees the handsome Pony Express Rider, Johnny, but her overbearing sister has determined that Maggie needs to find someone more fitting for her social standing.
Will Maggie win Johnny's heart, or will her sister put an end to the relationship before it starts?
