Kunjoonjamma Thomas (Padmini (actress)) is a widow living in the village all by herself. People always make fun of her because she is grumpy and depressed due to the deaths of her husband and her only child. Children irritate her by ringing her door bell and running away. One day, her granddaughter Girly (Nadhiya), who she had never met, visits her. Initially, Kunjoonjamma does not like Girly, but they soon become close to each other. Kunjoonjamma takes down the door bell, saying to Girly that its only purpose was for Girly's return. Now that Girly is with her, she does not need it.
