Leela and Bholaram are a childless couple. Leela works as a midwife, and one day assists Sunderdas' wife to give birth to twin boys. She decides to keep one baby for herself, and tells Sunderdas that his wife has given birth to one child. There are complications for the mother, and she passes away without seeing her children. Leela and Bholaram bring up Kanhaiya, while Sunderdas attempts to bring up Kishen, but is unable to do a good job. So he marries Kamini, who comes along with her brother, Ghendamal, to live at the estate. She has an illegitimate child named Mahesh from another man, and when Sunderdas comes to know of this, he is threatened and attacked, and as a result of which he is paralyzed, unable to move. Kishen is brought up by Kamini and Ghendamal with lot of abuse, and intimidation, and is kept illiterate, so that he can blindly sign away whatever documents he is asked to sign.
Kanhaiya is brought to be a street smart and a movie crazy young man. That's how he meets an equally movie crazy rich and spoilt girl, Anju and they fall in love. The one secret that ties the brothers together is their reflex action which means that if one is injured the other feels the pain too and only Bhola makes the connection at a vital point in the story. Kishen likes Radha, a servant, and is married, but the atrocities do not stop.
Finally Gendamal asks Mahesh to kill Kishen by throwing him off a cliff after getting the property papers. At the same time, Kanhaiya comes to know of his past and returns to the ancestral mansion shocking everyone. What also shocks everyone is his changed attitude. He denies his signatures on the papers signe by Kishen. Finally all the confusions are resolved and both Kishen and Kanhaiya together fight the evil and achieve justice.
