| France, 1815. Jean Valjean, a common thief, is released from prison after having lived a hell in life for 19 years, but a small mistake puts the law again on his trail. Ruthless Inspector Javert pursues him thorough years, driven by a twisted sense of justice, while Valjean reforms himself, thrives and dedicates his life to good deeds. In 1832, while the revolution ravages the streets of Paris, Valjean and Javert cross their paths for the last time. |
