The film is essentially about 3 people and their families. We have Arko and Rhea who lose their only child in an accident where he is run over by a bus, Kartick the bus driver who runs over Arka and Rhea’s son and Swapan Chakrabarty, the insurance surveyor who investigates the case. The accident shatters the couple and they find hard to face life , but they find a different meaning and purpose to life when Kartick approaches them one day. He is extremely guilty conscious and hates himself for what he is done, but he is actually not responsible for what had happened as the mechanism of the bus was faulty. The third person who has a moral conscience also is Swapan Chakrabarty, the insurance surveyor who investigates the case and sees the ‘system’ is at fault. When people unite and decide to take up a cause for mankind in general, the cause can actually be converted into reality , at least for the sake of the film. That is what happens because the trio decide to take up cudgels against the system which includes the bus owners, the union, the bus company and even the administration including the Transport Minister and the Chief Minister and accomplish their mission or purpose. The Chief Minister is forced to implement some changes which include salaries for bus drivers, no bus more than 15 years to be on the road, buses to be tried and tested before they are on the roads etc.
