Someshwar aka Dadamoni lives with his sisters Ratna, Reshmi, Rani and Rimli. As every year, he lifts the goddess’ palanquin on Bhubaneshwari Puja, hosted by Bhubanpur's patron, Parthasarathi Roy.
Someshwar explains the value of sisters to Botuk's sons and later asks Hori Kaka for a groom for Ratna. Meanwhile, Parthasarathi asks Parvati to return from the city where she studies medicine.
Someshwar’s bike hits Parvati’s car. A furious Parthasarathi decides to fix her marriage after seeing her ride with Someshwar. That night, Someshwar heads out to search for his drunken father.
Reviewing the horoscopes, Probhakar predicts Someshwar will marry before his sisters. Someshwar reflects on his childhood with Parvati, who, on the other hand, rejects the idea of marriage.
Parthasarathi visits the Sen mansion in Kanchangar and finalises Parvati’s marriage to Prodip with Kalyani Sen’s approval. Meanwhile, Hori Kaka brings a match for Ratna to Someshwar.
Shubholokshmi, Sulakshana and Parvati visit Someshwar’s house. He suggests Protap’s marriage to Rani, but Shubholokshmi dodges it. Parthasarathi tasks him with making Goddess Bhubaneshwori’s offering.
Someshwar’s sisters offer him birthday wishes. Later, he falls ill at the temple, prompting Parvati to tend to him. However, her actions offend Prodeep’s family, who leave the temple, humiliated.
After his sisters fall asleep, Someshwar calls Parvati to thank her and asks her to stay when Ratna’s suitor's family visits them. Later, his sisters sneak out for a movie while he’s fast asleep.
Someshwar whips himself as punishment after his sisters go to a movie without telling him. The next day, when the suitor’s family visits Ratna, Parthasarathi arrives and raises the topic of dowry.
Someshwar arrives at the Ray house in kurta dhoti with his sisters and is shocked to see another groom’s family there. He faces insult from Protap and Prodeep, and Parthasarathi ridicules him.
Parvati and Prodip exchange rings, but he demands she quit medicine after marriage. Someshwar’s insult angers his sisters, yet he lovingly credits Parthasarathi’s role in his life.
Someshwar visits Amlan’s house to discuss dowry for Ratna, but Amlan’s mother turns him away. Amlan offers him financial help, but is later humiliated by Protap in front of Ratna.
Insulted by Parvati’s behaviour, Prodip decides to call off the wedding. Meanwhile, Someshwar seeks a loan from Parthasarathi for Ratna’s marriage. His heartfelt care for his sisters moves Parvati.
With his entire family, Parthasarathi attends Ratna’s blessing ceremony. Later, Ratna is taken aback seeing Protap at home. Elsewhere, villagers gossip about Shibeshwar’s alcohol addiction.
When Someshwar’s mother’s character is questioned, Amlan’s mother calls off the wedding. As Someshwar comforts his sisters, Shibeshwar tearfully blames himself. Later, Amlan apologises to Ratna.

Someshwar arranges Ratna’s marriage with Protap. Parvati regrets Ratna’s fate and urges Someshwar to prioritise her well-being. Meanwhile, Protap pretends to be nice at Someshwar’s house.
Ratna agrees to marry Protap. Prodip informs Parthasarathi that someone sent a letter to break his marriage with Parvati. On checking it, Parthasarathi finds the handwriting matches Shubholokshmi’s.
Parvati ignores Parthasarathi’s warning and attends the medical camp. There, Someshwar handles a thug called Chhatrapoti. Meanwhile, Ratna writes a letter to Parvati expressing Someshwar’s feelings.
Someshwar plans to confess his feelings to Parvati with a rose but backs off when he sees Dr. Siddhartho proposing her. Someshwar’s sisters consult an astrologer about his horoscope.
Parthasarathi learns about Ratna’s wedding expenses from Someshwar. Parvati decides to marry Siddhartho at her friend Jamini’s wedding, while Parthasarathi instructs Someshwar to monitor Parvati.
Parvati and Someshwar attend Jamini’s wedding, followed by Someshwar’s sisters. Seeing Dr Siddhartho with Parvati there deeply hurts Someshwar. Meanwhile, Amlan arrives in disguise to talk to Ratna.
