Though, in the beginning the film claimed to be present a fictional story but actually it is a movie where some incidents were identical to the reality of a particular period of time.
I have seen the migration of Bihar and UP workers in the Corono time. It was a very tough time and government didn't arranged enough to deal with the situation. Many people suffered, some reached home and some didn't.
Previously, when the first trailer of the movie was launched it was corrected later with the removal of Prime Minister Modi's indirect and direct speech. Also, the film had to cut down some scenes. You can Google it for precise info on it.
I don't know why Censor board had to advice the filmmaker to cut some scenes and dialogues/words and portions of the films before its release.
It was the time when News Channels were somehow managed to spoil and brainwash the people of a particular community to blame other community for the spread of the virus. Which was absolutely a political move.
Many events were identical to real events which creates an assurance of recalling the biggest nationwide migration.
The way this film tells about the Hindu Caste system was Unfairly presented and overly exaggerated. Like we don't do it when there is a much important crucial situation to deal with.
Aso, In a scene where Muslim passengers of a bus were sidelined by Hindu people and they were alleged for the spreading of the virus, in other scene where a Muslim Priest offered food to Hindus and the food was rejected. The both scenes also plays a narrative. In a movie like this, the makers must have to balance out social norms and standards.
