Sharondza is right...
Daksha is the only daughter between 6 brothers. Their father put a fd on her name for like 25 crores or something for her future. 3 bhabhis were jealous of her (ketan and gautam weren't married then). All bhais paid attention to Daksha and not to their wives as much. There was a guy who worked in office, Prakash (I think that was his name). He was a bad person who stole and cheated the family. Bhabhis knew this and hired him to make Daksha fall in love with him. He slowly impresses Daksha and makes her feel he is a good guy. Here the family is finding a good relation for Daksha. Daksha finds out and cannot break the new to her father knowing that the family will be hurt and breaks up the relationship with Prakash.
On the day of the wedding, Prakash calls Daksha saying he is going to commit suicide. Bhabhis tell her to go and talk to him before he does anything. They hand her purse with jewelry, cash and her fd papers. She goes over to tell him to forget her. He says that only reason she is marrying someone else is so she can have the money that her dad has for her. If she marries him, her dad will take away the money. He leaves the house and she goes bhind him. Here bhais are wondering where she is and bhabhis tell them that she went to be with Prakash, they tried stopping but she left anyways. They go over to Prakash house and sees a pandit and pooja being done. Pandit says he just got 2 of them married (he was involved in this).
They go and tell the father and father get's heart attack. Mother is paralyzed with the shock. When Daksha returns she sees that her father is dead. Her whole family hates her and tells her to leave. Daksha goes to commit suicide but Prakash saves her and says he will marry her. They get married and next day Daksha goes over to bank and names her FD to Mohan's name that will mature after 8 yrs. When Daksha returns, Prakash is gone and even the house is empty. Daksha gets pregnant and she works to raise her daughter until Mohan finds her.
Hope this was clear enuf :) Let me know if u want further details about Daksha's return in house.
