Julienne Ashby, 24, must change her pampered ways after her father, a prominent businessman in Natchez, Mississippi, loses their fortune and family home to a bad gambling habit in 1850. Like a fish out of water, she aims to refit their one remaining possession, an old riverboat, in hopes of making a profit and restoring the Cuvier name along the mighty Mississippi. Desperate for help in doing the restoration work, prideful Julienne hires Dallas Bronte, a humiliated captain whose drinking problem stopped his water ways many years ago. Despite initial success, the struggles they will face with other ship owners are almost as challenging as the fiery feelings - of love and hate - that they must sort out for each other. When the riverboat and all aboard meet what looks like certain destruction, God shows Julienne and Dallas only one of those emotions is unsinkable.
