Karuthayya (Murali) and Peter (Manoj Bharathiraja) are the best of friends, sharing with each other their hopes and dreams. Karuthayya’s plan to get his beloved sister Kayal (Umashankari) married elsewhere is thwarted when he learns that she is in love with Peter. He hears this from Uppili (Pratyusha), who has a soft corner for Karuthayya and vice versa. For his sister’s sake, Karuthayya approaches Peter with the marriage proposal. A shocked Peter, who had all along shared an easy relationship with Kayal, consents for the sake of friendship. Peter then makes a counter proposal that Karuthayya marry his sister Maria. Peter however withholds the fact that Maria had been seduced by a man from the city and was carrying his child. Family honor being uppermost in his mind, friendship takes a back seat. But Peter does not know that Karuthayya was already aware of his sister’s affair, though not of her pregnancy. Karuthayya, knowing his friend’s aggressive nature, had not told Peter about the matter earlier. Karuthayya now throws the ball back in Peter’s court, asking him to first get Maria’s consent. Sure that Maria would not give her consent for the marriage. But to his shock Maria agrees.
Forced by her mother and Peter to toe the line, she had no other option. The two pairs get married. While Peter and Kayal are blissfully happy, Karuthayya and Maria have their own crosses to bear. A guilt-stricken Maria finally confesses to Karuthayya about Peter’s treacherous act. A shocked and hurt Karuthayya goes to confront Peter. The man from the city appears on the scene. A furious Peter takes the unsuspecting youth on a boat ride, ties a stone on him, and dumps him into the sea. Karuthayya, who reaches the place, tries to save the guy.

Dhinakar (Jai Akash), hailing from a middle-class family, and Nancy (Madhumitha), a software engineer and sole breadwinner for her family, are neighbors who are in love with each other. However, their dreams of getting married are shattered when their self-centered parents decide on proposals of their own choice. Notwithstanding the overbearing parental pressures, Nancy marries Victor (Prakash Raj), a multimillionaire businessman, while Dhinakar marries his cousin – but not before the lead pair enters into a sly pact. Dhinakar and Nancy contrive to marry the spouses chosen by their parents, only to officially dissolve their unhappy unions later and thereby pave way to their union. After a sequence of events, Nancy successfully convinces Victor about her unreserved enthusiasm for her past love, gets her divorce, and takes the first step towards making a fresh start, but events overtake her in an unexpected final act.

Rammohan (Harish Raghavendra), after five long years of saying ‘no’ to getting married, agrees to wed Gowri(gayathri raghuram) after seeing her picture. But he gets a shock on his wedding night when Gowri turns out to be the exact opposite of what he has imagined her to be. While he had thought she would be a traditional, homely girl, Gowri turns out to be an ultra-modern gal who even drinks. On the other hand, Kaveri(Uma), who Rammohan hires as his secretary at work, is the kind of woman he wished for as his wife. Meanwhile, Rammohan rubs Selvakumar(Arun Pandiyan), the new policeman in town, the wrong way and Selvakumar itches for a chance to get back at him. The time comes when Rammohan gets into an accident.
