In order to clear her brother of a wrongful murder conviction, an unemployed single mother puts herself through high school, college and law school.
It is a good logline. If something is missing, it is the sense of a timeframe. We know that her brother will be tried and put to prison, but how much time does she have, to go through all these stages of education?
Another thing: is this story’s main conflict her being illiterate and getting an education? If the story focuses more on the law school part, perhaps eliminate the high school part from the log line.
The movie was based on an actual legal case in the state of Massachusetts. Kenny Waters was convicted of murder and given a life sentence in 1983. So she had the rest of his life to achieve her objective goal. There was no ticking clock.
It took his sister Betty 12 years to get her law degree so that she could represent him in court. It took her 6 more years of challenges to the validity of DNA evidence used to convict him. (It was not a matter of corrupt cops so much as incompetent ones.) He was finally released in 2001 — 18 years after being wrongly convicted.
The main conflict is her battle against the local law enforcement agency and in the courts to prove her brother was innocent — that’s her objective goal. Getting the necessary education was the means to achieving that goal.
I didn’t see the need to add “in order to represent him in court”. It’s obvious, goes without saying. (Why else would she want to get a law degree?) So it need not be said in a logline.
