Narasimha, a young and captive man, lives a middle class life with his family in a quiet neighborhood. He gets his beautiful sister married to an eligible young man in their vicinity. On the occasion of his sister giving birth, he returns home to find a communal conflict arise between his neighborhood which spreads in the whole city. He seeks refuge in a dwelling area nearby only to return and find out his whole family has been murdered. With no aim left in life Narsimha decides to turn to crime and alcohol. He later decides to work for a man called Suraj Narayan Singh aka Bapji who is a big goonlord and capitalist of the city and basically controls the law and order of the city and rules over it using muscle power and his immense wealth . Bapji was delighted to get hold of a man like Narsimha who has wits and also muscle power but has lost desire to live and hence Narsimha executes his most difficult works which others can't accomplish. Bapji believes that he has become invincible and nobody can dare protest him since he has the city under his complete subjugation. He considers Narsimha as a weapon which can unlock his most difficult problems and a Narsimha, who is completely dejected from life, accomplishes them without asking any questions. Narsimha remains drunk full day and only comes when summoned by Bapji to execute Bapji's assignments and receive his payments.
However all humanity is not lost in Narsimha and he occasionally helps out people in distress. But he remains drunk most of the time and leads life solely on the money provided by Bapji. Bapji openly declared to the city that since he is so powerful, influential and rich, hence nobody can kill him, not man or animal, neither by weapons nor any device, not in day neither in night, just like the Hindu Mythological Demon King Hiranyakshapu who had obtained the same boon from Lord Barmha after long penance. Hence Bapji asks the people of the city to consider him as their Lord since he completely controls the money and the goon force of the city and practically rules the city as per his own wish. But when Bapji asks Narsimha to kill a young boy named Ravi Rastogi for falling in love with his daughter, Meenu, Narasimha refuses.Witnessing the love of the young couple as well as the revolutionary honest character of Ravi's sister Anita, humanity rekindles again in Narsimha and he joins forces with Ravi and his sister, Anita to force Bapji to get the young couple married. Narsimha openly conflicts with Bapji as he is the only one smart and strong enough to take on Bapji and is aided by his few loyal friends and Anita.The conflict escalates to very large extent and Anita, with Narsimha's help, was successful in rousing local help and mob support against Bapji's Oppressive and illegal rule. Bapji tries all the tricks in book to curb this rising opposition using his goons, muscle men etc. but is thwarted everytime by Narsimha. Narsimha even kills Bapji's famous wrestlers in Bapji's private court in front of entire city and showed the whole city that Bapji was afraid for first time and hence they need not obey Bapji from now on. Bapji was later arrested by police due to his illegal activities after being pressurized by the people of the city led by Narsimha and Anita. While being taken by the police, Bapji was humiliated by the people of the city who were fed up with his long tyranny and oppression.However,later he gets released on bail using his money and employing the best lawyers.
Bapji forcibly decides to marry Meenu and locks her up.He finally captures Narsimha and brings him to his palace. There Bapji informs Narsimha that it was him, who planned the communal riot which killed Narsimha's family since riots were necessary to keep the mob afraid and weak and hence aided Bapji in controlling the entire city. He then stabs a fuming Narsimha in his abdomen using his sword and wounds him fatally. Then he orders his men to bury a half dead Narsimha inside a pillar of his palace and plaster it up. Next morning, when he tries to forcibly wed Meenu, Anita and Ravi arrives with their friends to stop the wedding. However Bapji releases the prisoners of the Jail and hands them weapons to control the mob. When Meenu refuses to marry and instead comes to Ravi, Bapji orders both Meenu and Ravi to be plastered alive in his palace wall while their helpless friends watch being guarded over by armed criminals and prisoners freed by Bapji. Suddenly a wounded Narsimha breaks the pillar inside which he was plastered up thus fulfilling his name which is synonymous to the fourth reincarnation or avataar of Lord Visnhu who broke out of the pillar to kill the demon Hiranyakshapu when called by Hiranyakshapu's pious son Prahlad. Similar to Lord Vishnu's 4th avataar, Narsimha breaks out from the pillar and takes on the goons of Bapji while his friends and people also join hands to help Narsimha. He vanquishes the goons with the help of his friends and rescues Meenu and Ravi by breaking the wall in which they were plastered up.Breaking of the pillar and walls by Narsimha disturbs the foundation of the palace and its roof and other walls starts crumbling down. Lastly Bapji gets killed by the arms of the tower clock of his palace which breaks down and falls on him. Finally Anita and Narsimha unites and so does Ravi and Meenu and peace returns to the city.
