Once upon a time in Bihar is a bold take on the Maharashtra-Bihar political issue. It is based on true happenings which took place in the 2003 in Buxar district of Bihar. The problem of unemployment in the starving state is being raised in the movie. The movie displays the battle of the three central characters Rajiv Kumar (Kranti Prakash Jha), an IAS aspirant; Sankar Pandey (Deepak Singh), a young, harassed graduate; Jeans (Ajay Kumar), a dreamy, folk singer who believes his fate awaits him in Mumbai and how the atrocities of their lives force them to act against their true beliefs and values and also the revolution led by political leaders in Mumbai against Bihari migrants. The movie will change your ideas about the political system and will definitely leave you in thoughts about any political or social action of yours. All set to witness the harsh reality that the movie promises to bring forth about Bihar?
