The film starts off with the film’s Hindu protagonist Dharampal Trivedi (Paresh Rawal) irritatingly waking up to the ‘azaan’ from the nearby mosque. Despite all this, he leads a happy and content life with his two obedient children, a loving and caring wife, alongwith a ‘numero uno’ catering business. His immediate neighbor happens to be a Muslim lawyer by the name of Nawab Mehmood Nazeem Ali Shah Khan Bahadur (Annu Kapoor). And it is because of his annoying behavior and religion, that Dharampal hates him to the core.
Life goes smooth for Dharampal until his wife reminds him to open the bank locker of his dead mother. And when he opens the locker, his eyes get filled with tears to see all his childhood drawings that his mother had preserved through her life. In addition to this, he also finds a set of his mother’s gold bangles and an old affidavit. Life suddenly comes to an absolute standstill for him when he reads the affidavit which states that he was actually adopted by his parents and that he is a Muslim by birth. Fearing shame and disgrace, he hides this religious truth from his family. At the time of distress, he finds a confidante in Nawab Mehmood Nazeem Ali, who helps him trace his parents. Nawab reveals to Dharampal that while his mother is dead, his aging father is living in a Muslim sanctorum. Upon reaching the sanctorum, Dharampal gets stopped by the character played by a mullah (Murali Sharma). He imposes a ‘rule’ on Dharampal that in order to meet his Muslim father, he has to inculcate the mannerisms and behavior of a devout Muslim. That’s when Nawab Mehmood Nazeem Ali comes to the rescue again and starts training Dharampal in the same. Meanwhile, Dharampal’s son Amit, who is a ardent devotee of the ‘blue’ spiritual guru Neel Anand Baba (Naseeruddin Shah), wants his father to learn proper Hinduism in order to impress his girlfriend’s parents as her father is a staunch Hindu. All in all, Dharampal’s life becomes one royal mess when he starts learning the ‘mannerisms’ of both the religions simultaneously.
During a sudden turn of events, Dharampal accidentally attracts the backlash of Muslims who come out to attack him. Having left with no other options, he reveals in front of everyone (including his family) that he is actually a Muslim by birth, which shocks and stuns everyone alike. The revelation results in his family abandoning him. When left all alone, he stumbles upon a startling truth about Neel Anand Baba, which changes the course of the film totally upside down! What was it about Neel Anand Baba that changes the course of the film completely, does Dharampal’s family ever come back to him, does he ultimately manage to meet his aging father and does Dharampal’s son get to marry the girl whom he loves… is what forms the rest of the film.
