With a thirst for adventure and a new life, Katie Matthews heads west to Marietta, Montana to reconcile with her estranged sister and prove she's matured. But during her journey, her stagecoach is robbed leaving her destitute and on foot and later framed for theft, which lands her in jail. Not the ideal beginning to prove she's turned over a new leaf. Scott Taylor hitches horse and wagon to rescue his partner's sister-in-law from jail. But what he's not prepared for is the force of attraction towards this beautiful, fiery woman. When a hard rain sends them ducking for cover, his usual steadfastness is no match for Katie's charm and their mutual passion. Determined to make an honest woman of her, Scott insists they marry. Scott's devoted his life to being a strong, responsible, hard working cowboy who does the right thing no matter how tough, but when he comes face to face with his ugly past, he fears he'll lose what he's just discovered he can't live without.
