Three college friends, entirely different behaviors, are allowed to live on rent in a lodge ran by a mother, and her two daughters, reluctantly, to sustain daily living.

Kunjoonju, Deepu, and Ashtamurthy are studying hotel management at Pondichery. Kunjoonju is a 'Kanjirappally Achayan' who is always after girls. But his 'thrill' for a girl will end the moment he finds that she is interested in him. Abbas ,the trio's friend, arranges for them to stay in the top floor of a house owned by Sophy, who lives there with her two daughters, Kamala and Padma. All three guys fall for Kamala, but Kunjunju and Deepu join together to push Ashtamurthy out of the race by making him the 'Rakhi Brother' of Kamala, who knows that Kunjunju is a flirt, stays away from him. Deepu never tells about his love to Kamala or Kunjunju, but Ashtamurthy knows about it. Kunjunju and Deepu fall apart after a fight and Ashtamurthy brings them together. The story takes a turn when Sophy dies and the sisters are left alone..—tojo
