It’s about the triumph of human freedom and human conscience.
To achieve freedom, human conscience must wake up and play its part in action and thus in history.
In the eyes of those people who are entering a dark channel of history, this kind of optimism generates both joy and pain, both hope and despair. Since we don’t know how long it will take to go through this channel, whether we can make it, and whether conscience and freedom will win or not.
But the actors in the true story made their brave choices also in the darkness, unknowing the answers to above questions. So the true story is not just about humans’ craving to freedom, but about to gain freedom, what really needs is human courage.
Without courage, there is no freedom.
So, we are doomed.
