He will kill you with laughter till you cry for mercy
In the early
70's – Bombay was taken over by smugglers and gangsters. One of them
was Don Muthuswami. On his deathbed Don Muthuswami's father extracts a
promise from his son that he would go straight. Muthu decides to invest
in a legitimate company. He engages an Urdu/Hindi teacher Jaikishan to
improve his language. He thus starts his journey to change from Don
Muthuswami to Sir Muthuswami.
Now the only issue left is to get his
daughter Sanjana married and the best match according to him was his
very good friend Don Vardhan's son Pradhan. Sanjana however would marry
anyone but Pradhan.
Preetam, Muthu's general manager comes to Muthu
and asks for his daughters' hand in marriage. Muthu says his daughter
deserves a man who earns millions. Preetam claims to be a millionaire
and reveals that he became a millionaire by stealing from Muthu.
In
the meanwhile Muthu's daughter is desperately thinking of a way so that
she does not have to marry her father's choice.  She calls him and
tells him that she is pregnant. Muthu is shocked and concludes that
Preetam has made his daughter pregnant.
A cute girl, Ranjana comes
to meet Muthu and tells him that she loves his manager Preetam and
admits to Muthu that she had lied to Preetam about being Muthu's
daughter. Muthu is relieved that Preetam is not Sanjana's boyfriend but
now wonders who could be the father of her baby.
How does Muthu get
back the loot from Preetam? Who is the father of Sanjana's baby? Who
marries whom? Who Is Ranjana? What happens to the opposition gangsters?
How does Don Muthuswami handle the police?
