Kannathaa, an old rich countrywoman of character, as well as her husband, Vadjiran Subbaiya, an old hunter, look forward to the return of Selvam, their unique grandson, whom they raised with love, since the death of his parents. Selvam returns at his home, having ended his higher studies. In the train which returns him, he meets Seetha, also a graduate, who avoids her home, because of a marriage forced with a notorious procurer. Because he chooses to marry not with the one who was intended, he, by the good care of his grandmother, Selvam, exiles himself with Seetha, who has just married him, towards the capital.
The couple meets difficult debuts, because they are obliged to work in the same office, by pretending not to know each other. They have to face a multitude of qui pro quos. Then once reconciled with his grandmother, Selvam and Seetha is obliged to lie him, by presenting him a child who is not theirs. Indeed, Vadjiran Subbaiya who had come see his grandson, well before, leaves Seetha with a child in her arms. The old man deduced that it was theirs. Selvam "thus" "rented", with Anushya, her baby, to keep up appearances. But the young woman turns out to be a big swindler. She exploits the situation of the couple.
M. Saravanan who initially worked as production manager produced his first film Mamiyar Mechina Marumagal (1959). The film's failure left him upset and he decided to score a successful film in near future on the same subject which eventually became Paatti Sollai Thattathe.[1] The makers initially wanted Gangai Amaran to direct the film which did not work out. Saravanan decided to adapt Pattam Parakudhu written by Chithralaya Gopu after it was rejected by television channels.[2]Pattam Parakudhu was adapted from the 1968 American film The Love Bug.[2] The film featured a Volkswagen Beetle named "Super Car" that was inspired by Herbie, the car featured in The Love Bug.[3][4]
