Marty Claridge (Katherine Heigl) has just moved out to the West with her husband Aaron Claridge (Oliver Macready), who dies in a riding accident shortly after. Expecting her late husband's baby, Marty has nowhere to go and needs a place to stay through the winter. Desperate, she accepts the proposal offered by widower (Dale Midkiff). Clark offers to give her a place to stay for the winter and provide her with the fare for the wagon train heading back East in the spring. In exchange, Marty agrees to marry Clark and provide a maternal influence for his young daughter Missie (Skye McCole Bartusiak).
