It was a time for adventure... and a time for love. On the eve of the dangerously controversial Louisiana Purchase, Diana meets David, a handsome and charming French Creole aristocrat, at a gala New Orleans party. When her family sends her to St. Louis, until the threat of a Creole uprising against the Purchase is over, David follows Diana. In St. Louis, Diana meets John, a brave and bold Kentucky frontiersman who is about to leave with the Lewis and Clark expedition, which is being sent to explore the new territory. After the expedition departs and months pass without word of it, it is given up for lost. David wants Diana to marry him. But will saying yes to David be saying no to true love?
