This movie is a story of two friends, their families and the way their current relationship unfolds. The film begins by depicting the friendship between Avarachan, Thampi and Avarachans scheming Brother in law, Philiposes. United, they are an unstoppable force, doing everything according to Thampis brains and the strength of Avarachan. Their wives are pregnant, with each of them hoping for a girl child. Their wives go into labour at the same time, while Avarachan is away on an assignment. Thampi calls Mariyamma Chettathi, who is adept at delivering children. Avarachan is born with a boy child and Thampi with a girl. After the birth, Avarachans sister switches the babies as per Philiposes request. He then does the same, not knowing that his wife had done it before. Avarachan on returning finds that his wife has delivered a boy child, while she believes that she has delivered a girl. In reality, she has delivered a boy child, but neither she nor Thampis wife sure about the truth. This confusion leads to an issue between the two friends, ultimately resulting in a situation that Philipose planned. They both believe that the other friend has cheated, with Madhavan Thampi living in poverty compared against to Avarachan who lives in the lap of luxury. Their children Unnikrishnan and Alice respectively grow up as enemies and end up in the same law college. On the other side, Thomaskutty the adopted child of Philipose hopes to marry Alice one day, even though she has no intention of a relationship with him. A chance encounter with Mariamma Chettathi, the woman who delivered the children leads the families to realise that the children were exchanged at birth. They both return to their actual family, rechristened as Kunjuvareedu and Kalyaani. They devise a plan to bring the families closer by acting as if they are in love. The plan works perfectly, with both of them standing up for their love. In the end, they fall in love with each other in reality. Both families arrange for the wedding on the same day.

A terrible fight ensues and finally, Avarachan and Thampi patch everything up for their children. Everything ends well, with families united together at last.
