There is a village in Rohtak District. Risal Singh lives in that village. He has 6 daughters and his age is about 60 years. He needs a son to run his family further( Vans chalaney key liye). He catches hold of a middle man which are available now in most of the villages of Haryana. The middle man arranges a “Bihari Bahu” in 8000 Rupees. On the other hand buffalo of Murrah variety is having price of Rs 50,000 in Haryana.(Usually the women in Haryana have a misconception that when their number will decrease their worth will increase!)Bihari Bahu is hardly 17 years old. It took time for her to acclamatise to the atmosphere there in the family. There is another younger brother of Risal Singh, Fateh Singh, who is 56 years old. His wife died 30 years back and he donot have any children. “Bihari Bahu” is to look after both of these pahalwans of the family. There is Sanjay of about 25 years of age in the neibourhood. Bihari Bahu had some attraction towards him. One day Risal Singh sees her talking to Sanjay and she was beaten up ruthlessly. After one and half years Bihari Bahu became pregnant. Risal Singh was very happy to know that. Ram Das from that village was working as lab technician in a Community Health Centre. He examined the blood groups of Bihari Bahu and Risal Singh and Fateh Singh. Bihari Bahu had O+ve blood group whereas Risal Singh had A +ve group. The blood group of Fateh Singh was also A +ve. Things went on .Now Risal Singh was very kind to wards her. He managed with a doctor in the city for her Ultrasound and he was happy beyond limits when he knew that the child in the womb of “Bihari Bahu” is a boy. She delivered the baby and the house was full of joy. The lab technician tested the blood group of the new born boy also and to his great surprise the blood group of the new born was B +ve.He did not diclose this to Risal Singh. But when “Bihari Bahu” was told about it she just smiled and went inside.
