elementary school class movie about the south weevils in my hair

In the Summer of 1963, Flint, Michigan is home to the Watsons, a close knit family. When 15 year-old Byron’s antics go over the top, his parents realize enough is enough and they decide the family needs a dose of Grandma Sands' no nonsense approach in Birmingham, Alabama. So the Watsons load up their 1948 Plymouth Brown Bomber and head South. When they finally make it to Birmingham, they meet Grandma Sands and her friend, Mr. Robert and discover that life is very different there than in Flint. During that historic summer, the Watsons find themselves caught up in something far bigger than Byron’s antics; something that will change their lives and country forever.

The time is 1945-46. 10 year old Eda and his friend Tonda live in a small village outside Prague. In school, their class is so wild and indisciplined that their teacher quits and is replaced by the militant Igor Hnidzo. He is very strict – but also very fair. His weakness though, is his interest in young women.
