Proud, wealthy, and haughty Kiran meets down-to-earth middle-class college student, Shekhar, and after several clashes and misunderstandings, both fall in love and decide to get married. Shekhar meets Kiran's dominating mother and docile father, and is told that he must successfully pass a test that by Kiran's mom, to which he agrees and subsequently passes, much to Kiran's delight. The wedding is performed with great pomp and ceremony and Shekhar becomes a ghar jamai. He soon realises that his presence in Kiran's house is next to a lowly servant. He rebels and wants Kiran to leave with him. But Kiran asks him to be patient. Thereafter, she gives birth to identical twin girls, Ganga and Jamuna. Shekhar still feels that they would be better off living away from Kiran's mother. Differences arise between husband and wife, and Shekhar moves out with an infant Ganga. Years later, Ganga and Jamuna meet at a school outing and both decide to switch places to get to know the other's parent. Both girls then devise a scheme that will bring their proud grandmother to her senses, and bring their parents to reconciliation.
Do Kaliyan was produced by AVM Productions. It is a remake of the studio's own Tamil film Kuzhandaiyum Deivamum (1965), itself based on the American film The Parent Trap (1961). Kuzhandaiyum Deivamum's director duo Krishnan–Panju returned to direct the Hindi remake.[2]Kutty Padmini, who portrayed twin sisters in the original, was initially signed on to reprise her role, but later replaced with Neetu Singh due to conflicts Padmini had with AVM.[3][4]
Do Kaliyan was a major commercial success and, according to film historian Randor Guy, "further brightened the radiant image of Meiyappan and AVM Studios".[2]
