Hum Saath-Saath Hain

While trying to save Prem and Vinod from a probable accident, Vivek is injured leaving him handicapped due to his right hand paralysis.

Prem returns from US after completing his studies. Sangita lives with her husband Anand and daughter Radhika. Vinod is busy in studies. Vivek is still in treatment for his hand. On Ramkishan and Mamta's anniversary function, the four siblings wish them with respect.

Seeing Vivek's love for them, Ramkishan's business associate Adarsh's daughter Sadhna likes him at first sight. Adarsh sends a wedding proposal for her. Vivek agrees and marries Sadhna. Vinod is secretly in love with Sapna (daughter of Ramkishan's colleague Dharamraj Bajpai).

They show the love of Prem and Preeti (daughter of Ramkishan's friend Pritam). Everyone agrees to engage them. Eventually, Prem and Preeti find out about Vinod and Sapna who get engaged too. Ramkishan makes Vivek the managing director of his company.

A bitter turn comes when Anand's brother Anurag cheats on him from inheritance and share in the family business. This incident triggers insecurity in Mamta's mind. Meanwhile, her three friends and Dharamraj fill her head with thoughts as to why Vivek should be in charge of the family inheritance. This makes Mamta very paranoid.

She questions Ramkishan's decision, and wants division of the business equally between all sons. He disagrees as it will divide the family. Heartbroken after finding out, Vivek asks Ramkishan to put Prem in charge of family empire and moves back to their ancestral village Rampur with Sadhna. Vinod accompanies them.

Prem refuses to replace Vivek as head of the family. Vivek convinces him to go along with plan in the interest of preventing further conflict within the family. Prem tells Mamta that he won't marry and can't replace Vivek if she wants so. Eventually, Anurag realizes his mistake and unites with Anand.

Sangita asks Mamta to bring back Vivek. Mamta realizes her mistakes and visits Rampur with Ramkishan. In the hospital, Sadhna delivers a boy. Later, Prem and Vinod marry Preeti and Sapna. Dharamraj apologises realising ill-manner cannot end the love in family. All live happily ever after.

Salman Khan, Mohnish Bahl, Reema Lagoo, Alok Nath, Himani Shivpuri, Satish Shah and Ajit Vachani who all were part of Barjatya's Hum Aapke Hain Koun..! were cast in this film. Among this Salman, Lagoo, Nath, Bahl and Vachani appeared in Barjatya's Maine Pyar Kiya too.

While discussing Bahl's role, it was first offered to Anil Kapoor and Rishi Kapoor but upon their refusal Bahl was cast to play Vivek and prepared it by making a habit of keeping right hand in pocket accordingly the role.

Barjatya initially approached Madhuri Dixit for Sadhna's role, who played the lead actress in Hum Aapke Hain Koun..! but declined owing to her popularity, and then Manisha Koirala got the offer; even she was unable to take it due to filming for Mann, before Tabu was chosen.

Later, the makers talked with Rishi Kapoor again for Anand's role, but his refusal came again as did by Nitish Bhardwaj when offered too, and thus Mahesh Thakur was roped in.

The maximum principal photography of the film was done in Film City, Mumbai, and left portions were shot in Jodhpur, Rajasthan like the song "Mhare Hiwade Mein Naache Mor".[9]

During the Jodhpur film schedule, some members of the cast, Salman Khan, Saif Ali Khan, Neelam Kothari, Tabu, and Sonali Bendre, were involved in a case of shooting of an endangered black buck on a hunting expedition.[10][11] The incident generated significant press coverage, and Salman Khan spent a week in Jodhpur jail in 2007, before the court granted him bail.[12] In 2018, the Jodhpur court convicted him and acquitted the others.[13]
