Hum: I'm Because of Us

Her Royal Highness, Princess of Daulatganj, Rooprani Kapoor marks her 25th wedding anniversary. She is fond of revisiting old memories of her late husband. After all, the marriage gave her three lovely daughters, Devina, Isha, and Sakshi. The three sisters leave for Mumbai when they receive an invitation to Vikram Bedi's 50th Birthday party.

New to the city, the three sisters set out to explore Mumbai as well as to search for means of livelihood. But Rooprani has one condition - it better be a respectable job. While Isha believes her charm can take her places, Devina emerges stronger after facing several rejections. At the end of a difficult day, the man of Devina's dreams comes to her rescue.

So far, Mumbai has been treating the Kapoors just fine. While Isha chooses to soak in the city's energies, Devina tries her best to fit into her job as a waitress. But, it also troubles her that she is forced to hide this truth from her mother. At the same time, she is certain that Rahul will keep her secret safe. However, a tense dinner table conversation at the Bedi's threatens to reveal a different side of the Kapoors.

Rooprani Kapoor has always lived life on her own terms. Keeping this in mind, she makes an important announcement. The sisters regale at their mother's decision. It's a promise of a new life - full of hard work, unexpected gifts, and a few skirmishes of the egos, as Pammi is not happy with the sisters' growing closeness to Mr. Bedi.

Rahul's friendly ways impress Devina, as she begins to fall for him. But does Rahul feel the same way for Devina? Whatever be his true intentions, Isha warns him not to play with her sister's feelings. There will be consequences he won't be able to handle. How long will the bond of the three sisters last?

It's time for the girls to let loose. At a party, Devina and Isha drink, shake a leg, and let go. The dance floor witnesses some cool moves and lots of jealousy. Rahul dances with Devina, and Isha enjoys with Mr. Bedi. But when it comes to choosing between a boy and her sisters, Isha is very clear where her loyalties lie. Should Rahul be worried about his intentions?

Rahul meets Devina knowing that the only way to get to Isha is through her. Devina's heart is breaking but she promises to talk to Isha on Rahul's behalf. Isha is happy to know what's on Rahul mind. So, when Rahul proposes she accepts. But Mr. Bedi has other plans for her.

Isha faces the big decision of choosing a life partner. No matter whom she chooses, her entire family will face the consequences. Both Rahul and Vikram are ready to wait for her answer. Since leaving Mumbai is not an option for Isha, she must make a choice. At a party thrown by Rahul, everyone hopes Isha will take the right step.

Marriages are made in heaven, but choosing a wrong partner can make life a living hell. Devina fails to make Isha understand the consequences of her decision. Devina takes it upon herself to save the two people closest to her from ruining their lives. On the other hand, Pammi can't see her brother Vikram make a grave error in choosing his life partner.

Isha and Vikram start preparations for their wedding. But those around them are not yet ready for this alliance. Even Pammi's calculated attempt is spoiled by Isha's smart counter. But Pammi doesn't give up and invites Rooprani to Mumbai. How long will the sisters manage to keep their mother in the dark about Isha's choice of husband?

Finally, everyone accepts Isha's decision of marrying Vikram. With dance and music, they all gather for the Sangeet ceremony of the couple. But before Isha can tie the knot with Vikram, she must sign some papers. Is Vikram's love for Isha conditional? Meanwhile, Rahul learns the identity of the man who broke Devina's heart.

The day of Isha and Vikram's wedding finally arrives. Isha is a reluctant bride who gives everyone a scare by running away from the wedding. Rahul and the Kapoors are delighted at the prospect of a cancelled wedding.

Devina and Rahul go on a dinner date. Isha arrives at the restaurant and walks out with Devina while accusing Rahul of being revengeful.
