When a handsome young man comes to tell Frannie that her mother is very ill, she wants nothing more than to go home. But her kind messenger assures her that he will take care of everything. Touched by his concern and sensitivity, Frannie’s love for him begins to grow. There is only one problem: He is from the wealthy side of the river, and she is from the poor side.
