Two days before the wedding, Kathiresan receives an anonymous letter inviting him to an abandoned bungalow. He goes and, in the cover darkness, fights an anonymous foe. At the end of it, he finds at his feet a body with a knife sticking out of its back! He leaves the place hurriedly. The next morning, Kathiresan, shocking everyone, screams at the bride saying she is not of good conduct and refuses to go ahead with the wedding rituals. Meanwhile, police enter the scene, looking for the bridegroom who escapes. With the marriage stopped in a dramatic fashion, problems arise in the unhappy Viswanath's family. How they are solved and the marriage is performed forms the rest of the story.

Kalyaniyin Kanavan was released on 20 September 1963,^[3] and did not do well at the box office as it ran for 10 weeks in most theatres.^[4] T. M. Ramachandran wrote in Sport and Pastime, "The film keeps up a breezy pace but it is obvious that when the director found that he had used up a good deal of footage early on, he has put an abrupt end to the story by untying all the knots in the plot all of a sudden and providing a happy solution".^[5]
