Sounder (movie, 1972)

The Morgans, a loving and strong family of Black sharecroppers in Louisiana in 1933, face a serious family crisis when the husband and father, Nathan Lee Morgan, is convicted of a petty crime and sent to a prison camp. After some weeks or months, the wife and mother, Rebecca Morgan, sends the oldest son, who is about 11 years old, to visit his father at the camp. The trip becomes something of an odyssey for the boy. During the journey he stays a little while with a dedicated Black schoolteacher.
