90s TV Movie Title Help

Trying to find the name of this tv movie I saw in the 90s. It may have been on Lifetime. The beginning took place in the 60s or earler where a young white girl befriended a African American boy. He later was lynched by the KKK and the girl’s older brother who was a Klan member. The older brother tried to silence his younger sister by drowning her. She survived but became brain damaged. Some years later, the girl becomes an middle aged or older woman and has a older boy and maybe a young couple as friends. She can’t or has trouble speaking from the brain damage. Her brother I think comes back or is released from prison and tries to come back and murder his sister. Her friends help find and apprehend the brother before he can murder his sister. The climax may have taken place during a town carnival or fair.
