"Vivah" is Marriage - an institution that binds tow individuals into a bond that is sacred, pure and eternal - a commitment for life.

Poonam (Amrita Rao) is an upper middle class girl who lives in the small town of Madhupur. After the demise of her parents, when she was very young, her Chacha (Alok Nath) fulfilled the void of a father in her life. But her Chachi (Seema Biswas) was unable to accept Poonam as her own child as Poonam was more beautiful that her chachi's own daughter Rajni (Amrita Prakash).

Poonam was blossoming into a beautiful and radiant young lady embellished with all the right virtues one could ask for. Her simple and affectionate demeanor touches the heart of Bhagatji (Manoj Joshi), who plays our matchmaker. Bhagatji takes Poonam's marriage proposal to Mr. Harish Chandra (Anupam Kher), a renowned and well-to-do New Delhi businessman, for his son Prem (Shahid Kapoor).

Prem is the soft spoken, charming and well-educated young scion of one of New Delhi's most prominent business families. In spite of being brought up in the fast city life of New Delhi, Prem is rooted to the ground and has retained his family's traditional values and upbringing. It is these qualities that make him stand out in today's day and age. When his father takes his opinion on the proposition, Prem is initially taken back and feels he is too young for marriage and needs to focus on his career first. But being open minded and respectful to his father's wish, Prem agrees to meet Poonam, know her better and then take a decision.

What follows is a 'meeting' arranged by the two families. Prem and Poonam are suddenly in the midst of a situation they have never been in before. What starts off as an awkward, formal exchange of words, grows into a deeper, meaningful conversation. Prem and Poonam discover their soul mate in each other. They are engaged - to be married in six months.

Prem and Poonam go through the most magical and romantic period of their lives. Both realise the importance of the engagement rings that they have given to each other and the special right that they have got o0n each other in return. Coming from different sensibilities, both want their relationship to be very 'right' for each other. Six months fly by and just when everything was set for Prem and Poonam to get married... a crisis puts the love of Prem and Poonam through a trial by fire.

What is a heart-warming tale of unconditional love...
