Documentary in which Indian filmmaker Lalit Vachani retreads the route taken in the 1920s by Mahatma Gandhi as he led a march that was to change India's destiny. His famous Salt March saw him walk 240 miles to Dandi in Gujurat, where he broke the British ban on Indians making salt and started the slow journey to independence. Vachani tries to see what Gandhi would make of the modern India, the biggest democracy on Earth, and he finds a country still riven with caste divisions and racial tension.
