Shawshank Redemption (月黑高飛)
The film is about a man who accused of killing his wife and jailed.
But he never gave up and always have hope to leave the prison.
He met many prisoners there, some become good friends and his philosophy of life had changed other prisoners thinking.
I will not give the end of the story cause it is really good and I highly recommend to watch yourself.
Actually, I think this is the best film I have seen for the past twenty years.
