It's 1955 and Sam leaps into the body of 16 year old Billie Jean Crockett who is also 8 and a half months pregnant. Her mother is dead and her father wants nothing much to do with her. Her boyfriend, who got her pregnant, is off to college soon and wanted her to have a termination. Al tells Sam that she will have her baby within a day and give it up for adoption leading to a lifetime of regret and searching for the child.
