Ek Duuje Ke Liye is about the love between a Tamil man, Vasu (Kamal Haasan), and a North Indian woman, Sapna (Rati Agnihotri), who are neighbours in Goa. They come from totally different backgrounds and can hardly speak the other's language. Their parents despise each other and they have regular skirmishes. When Vasu and Sapna admit their love, there is chaos in their homes, and their parents reject the idea .

As a ploy to separate the lovers, their parents impose a condition that Vasu and Sapna should stay away from each other for a year. After such a period, if they still want to get together, they can get married. During the year there should be no contact between them whatsoever. Vasu and Sapna reluctantly agree to the condition and decide to separate.Wikipedia
