Jeevanantham "Jeeva" is a rich youth who has just completed his B.Com. Although his parents want him to marry a girl and settle down, Jeeva prefers to pursue MBA studies instead and is not interested in marriage. But his attitude changes when he meets Mini, a Christian girl who is a final year B.Com student, at a book store. He instantly falls in love with her. After a few incidents, he succeeds in winning Mini's heart.

However, Mini's elder brothers, a doctor named James, a police officer named Stephen, and a local goon named Thomas, who are all overprotective of her, eventually find out about their sister's relationship with Jeeva, and are furious. They thrash Jeeva, as well as his friends Kesavan and Raghavan, and warn Jeeva never to come near Mini. Undaunted, Jeeva takes Mini to his house, where Jeeva's father Rajshekhar too disapproves of their relationship, and throws them out of the house. Kesavan and Raghavan take the couple to their slum near Pondicherry, where Kesavan explains their situation to his father, who is a fisherman. Kesavan's father agrees to let the couple stay in his house, and also defends them from Mini's brothers, when they come to the slum to kill Jeeva. Later, Kesavan's father decides to get Jeeva and Mini married, but by now Jeeva and Mini have developed second thoughts about their relationship as their families are against it. They decide to break up and return to their families, which is accepted by Kesavan, his father and Raghavan. But despite breaking up, Jeeva and Mini cannot forget each other.

Meanwhile, Mini's marriage is fixed with someone else. Jeeva's mother decides to meet Mini before she gets married, so that she can get a better wife for Jeeva. Jeeva, his parents, as well as Kesavan and Raghavan, go to Mini's house, where both families apologise to each other for what had happened. But when Jeeva and his family are about to leave, Jeeva's mother breaks down and requests Mini's family to get Mini married to Jeeva. Mini's family, including her brothers, agree to this. Jeeva and Mini are happily reunited.
