This is a pre-civil war and civil war movie.
It stars Walter Huston, Beulah Bondi and Jimmy Stewart as a minister's family with little money and a number of misunderstandings between Father Ethan and son, Jason. The mother, Mary, ends up trying to be the constant peace keeper.
Ethan wants his son to be a preacher. The dream of Jason's heart is be a doctor. Mary loves her husband but wants to see their son happy in the life's work he desires to do. Jason is to self-centered to see what his bickering with his father is doing to his mother.
In anger Jason runs off. Goes to school and then war. His mother doesn't hear from him for several years and she finally contacts President Lincoln (John Carradine) to learn where her son is and if he's alright.
Lincoln's reaction is predictable since we must remember Lincoln lost his mother, Nancy, at a young age. Now a decision must be made on what Jason will do. How much has he grown up? Will he realize he has broken his mother's heart?
It's at least a big box of hankies movie for all of us.
