The film revolves around the life of two 1971 immigrants.

The chief assistant director of the film is Madhuchhanda Sengupta.^[8] It stars Mithun Chakraborty and Debashree Roy in the lead.^[9][10][11]

The film created ripples upon its release and received moderate reviews from critics. It received 7.3 rating out of 10 on Mubi.^[12] Chakraborty's portrayal of Manik Mondal was well received by the critics once again generating the speculation that he well perceives the marginalized impulse.^[6][13] The film won Chakraborty his first Anandalok Award in the category of the best actor in a leading role, in 2001.^[14] It was not a financial success.^[13]

Manik is in love with Jhumur and intends to marry her. Manik and Jhumur often meet and hang around. Though he is an ordinary labourer who leads a poverty-stricken life, he becomes a significant financial help for the upcoming wedding of Bhadu, Jhumur's sister. One day he comes to know that Jhumur is in love with another man but her mother Jaba does not want her to reveal it before Manik. Jhumur's mother fears that Manik may quit helping them if the truth is revealed. Even though Manik is now aware that he has so long been exploited by Jhumur's mother, he does not turn outrageous nor he stops helping the family. He visits a brothel and falls in love with a beautiful prostitute Tagar whom he marries even though she reminds him that she is a fallen woman who has no social dignity.

17 years later, Tagar runs a poverty-stricken family. They have a daughter Purnima who is suffering from thalassemia and a boy named Babua. Manik has become jobless because of lockdown in his factory. He has contracted tuberculosis and become frustrated. Tagar works as a maid in Sujato's house. The latter moves by a wheelchair. Tagar, one day, wants to know how much it costs to buy a wheelchair. Sujato who feels compassionate towards her, arranges for a wheelchair free of cost. The arrival of a wheelchair leads to Manik's suspicion. He assumes that she has an illegitimate sexual relationship with Sujato and this is why she can afford to buy more for their family. He grows abhorrent of the life he and Tagar have and intends to assassinate his family after coming across a newspaper report of a labourer assassinating his family and then committing suicide. When he attempts to strangle Tagar, she urges that she wants to live and struggle for her family. Her urges revive his conscience. Once again they resolve to struggle together.
