Atal Jaler Ahwan is a Bengali drama film directed by Ajoy Kar[1] based on a story of Protiva Bose.
[4] Sreemonto Choudhury is a successful businessman but is a lonely person living with his only son Jayanta who has just returned from abroad with a degree in engineering.
Meanwhile, socially awkward and mentally immature Sabitree meets with an accident while roaming aimlessly on city streets.
As it has been one of Choudhurys' trucks to knock her down, she is admitted in hospital under the guardianship of them and post-discharge Jayanta has to give her shelter in his mansion as Sabitree becomes amnestic due to head trauma.
A few days later, the family physician warns Jayanta about the potential difficulties he may face for keeping Sabitree in his home and that this unknown girl who is taking care of everything may have dishonest motives.
