75 years old Biswanath Majumdar is in the publishing business. His wife, Arati is 66 years old. The couple has been married for 49 years and have been blessed with four children: their eldest son Barin, followed by three daughters, Malasree, Kaberi and Piu, all of them now married to Sharmistha, Bijon, Jyotirmoy and Palash, respectively. Internally, there's trouble in the siblings' married lives. Sharmistha, a medium-scale cloth merchant, is unhappy with Barin's financial position as his father's assistant in the publishing house and suspects that Barin is conducting extramarital affairs. Malasree, an outspoken modernist, doesn't consider Bijon, an unemployed man who lives off his rich inheritance & a
sarod-player by passion, to be smart enough for her, so she gets involved in an extra-marital affair. Jyotirmoy, a gold trader, is unhappy with the constant refusal of Kaberi, a mother of three, to satisfy his sexual urges. Palash, being involved in the
Bollywood as a director, has very little time to devote for his assistant-cum-wife Piu. On the night of
Vijayadashami after
Durga Puja in their
North Kolkata residence, in front of the gathered family, Biswanath Majumdar declares that he has decided to divorce his wife, and their mother, Arati. However hard the children try, they cannot extract any information from their father. Their mother seems unconcerned about the announcement. Biswanath files a divorce case in court. In the court proceddings, Biswanath declares that he wants to divorce Arati because he believes that their married life, having fulfilled its purpose, has been converted into a series of obligatory chores, which he wants to be freed of by starting life afresh. The judge, however, asks them to spend a 15-day vacation together, after which if they want, they can mutually divorce. Unsatisfied with Biswanath's explanation, Barin and his three brothers-in-law place
CCTV cameras in Arati and Biswanath's room to eavesdrop on their conversation along with their spouses in order to discover the real reason behind the divorce. As Biswanath and Arati share their long experiences of living together – their grudges, their disappointments, and their delights – they realize that despite having very little or no emotional connection with each other for prolonged periods due to Biswanath's busy schedule and Arati's involvement in household chores, they continued to care for each other. It's drastically different from their children's actions, who have adapted to the modern lifestyle and are whimsical regarding their marital lives. As they see their parents, the siblings discover their own follies and the love is rekindled with their spouses. Subsequently, Biswanath convinces Arati to divorce him to make her self-dependent, at which Arati unwillingly agrees and the two separate. However, after four months, Biswanath finds out that Arati has managed to be self-sufficient, but he cannot get rid of his dependence on her & suffers from
loneliness, so he returns to Arati. The two reconcile emotionally and the entire family, with renewed love in their respective married lives, happily observes Biswanath and Arati's 50th marriage anniversary. == Cast ==
