Maribelle is asked to leave the orphanage at age eighteen, she isn't sure where to go or what to do, so she jumps at the chance to ride the Orphan Train and help take care of the twenty-four children. At the final stop in Missouri, she is once again concerned about her future return to Boston, but when a handsome man asks if he can 'adopt' her to help take care of 'Connie', she immediatly agrees. Will Maribelle, 'Belle' find a home and love in Missouri or have to return to the orphan life in Boston?
