[citation needed] Actor Zayed Khan makes his television debut with this show.

[2] Haasil is the story of two brothers Ranvir and Kabir Raichand, whose lives get entwined with the entry of a smart and righteous lawyer, Aanchal Shrivastav.

Ranvir—the older brother—is a rational, generous, and selfless tycoon while Kabir is the opposite—protective of his loved ones (especially his brother) but a playboy.

She runs an NGO and takes up a case of a kidnap & murder victim, who turns out to be Ranvir's secretary.

However, Kabir brings evidence into the court, implicating the victim's boyfriend, who teamed up with her to con the Raichands for money.

Initial misunderstandings are cleared up and Ranvir hires Aanchal to work for their company where she rubs off his cousin, Gaurav, the wrong way.

Naina also has an ulterior motive because she wants Kabir's money to repay the debts incurred by her brother Rohan.

He suggests that Aanchal marry him first so that the prediction of her first husband's death is fulfilled and she and Kabir can live happily ever after.

But Ranvir is the master manipulator—he bribed the family priest (pandit) to make the false prediction, manipulated Gaurav and then killed him, and then faked a brain tumor—all for Aanchal.

Ranvir manages to fake his way through the operation and is released from the hospital after an apparently successful surgery.

After Kabir asks his brother to let Aanchal go, he finds out that Ranvir is planning to move to Mauritius forever.

His father asks him to leave the house, all the while knowing the reasons for Kabir's actions and keeping them hidden from Sarika.

He bribes a worker to add rat poison in the food catered by Aanchal's mother, Rupali.

But as it turns out Kabir has seen this news and doesn't board his flight to Mauritius but instead goes to rescue Rupali and Aanchal.

Sarika is unhappy and it is revealed that she killed Kabir's mother by pushing her off the terrace years ago, in order to become part of the Raichand family.

When Ranvir doesn't let Aanchal take the body for post-mortem, she investigates and is convinced that he is the murderer.

Ranvir reveals his true colours to Kabir and Aanchal takes him to the hospital when blood comes out of his mouth.

Kabir threatens Dr Agnihotri, bribes everyone working for Ranvir and they all turn to be on his side.

Dr Agnihotri informs Sarika that Aanchal (who is faking her mental state) must go to rehab.

Ranvir kicks Sarika out of the Raichand house because of her wrongdoings over the years and severs ties with her.

Aanchal regains her consciousness and recalls taking help from Dr. Agnihotri to slow down her heartbeat and breathing and replacing the bullets in Ranvir's gun by blanks.

As the happy couple leave the centre, the last shot is of Ranvir, looking sinisterly at them, implying that he is pretending to be in a mental state.
