Mangalam and Kannamma point out Durai's hypocrisy and duplicity in pursuing acting when he has such strict expectations of everyone else.
When Thangavelu confronts him, Durai lies and invents a younger twin brother, Raja, that is an actor and singer.
Thangavelu and his family fall for his act and hire Raja to be Kannamma's music teacher.
In the meantime, Vani falls in love with Chandran, Durai's co-star in his plays and also Thangavelu's nephew.
Durai confesses all to Thangavelu's family and is forgiven but now has to face the ire of Chandran and Bhavani.
