[4] Mahadevayya is a businessman who has lost his wealth by gambling, where he approaches his old friend, Rajaram, on the day of his only daughter Prema's birthday celebration to ask for a sum of ₹2 lakh (US$2,300).

On the same day, Rajaram's nephew, Shrikanth threatens to destroy his life if he doesn't conduct his marriage with Prema in a week's time.

After the party ends, a dispirited Rajaram receives a phone call from an anonymous caller, who threatens to provide ₹2 lakh (US$2,300) within a week's time in exchange for Prema's life.

While discussing about these incidents, the family receives a surprise in the form of CID Inspector Vijay, who claims to have been sent to solve the mystery and volunteers to stay in the home with a different identity to catch the culprit, where he develops a liking for Prema and soon they fall in love with each other.

A successful businessman from Mercara town, Seetharamaiah, is blackmailed by Shekhar, a hippie, and brother of Shakuntala, a young girl who was molested and impregnated by the former.

Shekhar coerces him to grant a monthly salary of ₹2,500 (US$29) in addition to a comfortable stay in his house as his multi-millionaire friend's son.

Seetharamaiah's wife is impressed by Shekhar, who in turn decides to choose him as a groom for her only daughter Bhaama, who however loves a professor from Mysore.

Years later, Sridhar returns from Delhi as an arrogant and spoilt young man who has no respect for fellow human beings and considers his step-mother, Savitri, as his nemesis much to the anger of Giridhar who loves her.

After receiving a trunk call from her lawyer, they travel to the nearby private hospital and gets to know that Giridhar got a mild stroke the day before.

The next day they receive a letter from a woman named Rani who addresses herself as the wife of Sridhar who is unaware of her husband's death.

He is surprised to know that the woman claiming to be Rani is indeed Shakuntala, whom he had molested a few years back but doesn't reveal the truth after she secretly informs Seetharam that his daughter, Bhaama is under her custody.

Seshgiri manages to subdue them and takes her to the house where Rani, Bhaama and Prema secretly resides and in their presence he reveals that he is the real Sridhar.

Feeling suspicious about Rajaram, Sridhar poses as Vijay and raids his house from where he receives a letter mentioning about the fake Sridhar/Kamalakar.
