The film is a story of a group of friends and their courage, romance and sacrifice at a fateful time. It is set in the fictional city of 'Falakabad' in the country of 'Mulke Khudadad'. In Falakabad, the story revolves around Yaadgaar Colony. Mulke Khudadad drifts towards anarchy, civil strife and a dark age. Political parties, leaders and lobbies pursue their own agendas. Corruption is at a record high, law and order have deteriorated. Inflation and unemployment are rampant, and intolerance is the order of the day. Deprivation and desperation set the stage for dissent. Confusion and chaos are voiced in the mainstream media, leading to disillusionment. The people wage a daily war for survival, with no time for ideas for the common good of the people. A group of friends are led by circumstances to try to change the future of the country. They form a political party despite their lack of experience, resources or political background in politics, but their efforts seem doomed. Faced with threats, arrest, cynicism and rejection, electoral reforms give them the impetus to continue. Under the new electoral system, 'Chambaili Tehreek' wins by a wide margin and its elected president gives his "Freedom Speech".
