Jayantilal "Ratan" Pandey (Deepak Shirke) is a ruthless criminal. ACP Sanjay Path "S. P." Malhotra (Dalip Tahil) arrests him. Ratan wounds himself and is taken to the hospital, where ACP Malhotra is waiting for his wife Geeta Malhotra (Reema Lagoo), who is in labor. She gives birth to twins. The doctor explains that both babies have a reflection mentality, which means that "what happens with one baby might be felt and reflected by another," depending on the proximity between them. Ratan escapes and takes one of the twins with him, injuring Geeta. ACP Malhotra chases after him. Unable to find his son, shoots a fleeing Ratan in an attempt to stop him. The kid grows up as Raja (Omkar Kapoor, then Salman Khan) and finds a girl, Neelam whom he adopts as his sister. He finds another orphan, Rangeela Prakash (Siddhanth Kapoor, then Shakti Kapoor) and becomes his friend. Together they take care of the girl and become small-time thieves.
On the other hand, Geeta goes into depression and gets paralyzed. ACP Malhotra takes her to the US for her treatment, where the other twin named Prem Malhotra (also Salman Khan) is brought up. He comes to India as a rock star for a show. He is received by Kishan Sharma (Kader Khan), who is his father's friend and wishes to marry his daughter Mala Sharma (Karisma Kapoor) to him. But Mala is in love with Raja. At the airport, Prem finds Roopa Batwani (Rambha), daughter of Sundari Batwani (Bindu), the organizer of his public shows. Prem falls in love with Roopa. Tony (Jack Gaud), Sundari's nephew, also wishes to marry Roopa. Meanwhile, Mala misunderstands Prem for Raja and starts flirting with him. One day, Raja and Prem see each other in a restaurant and find out that they are identical, which leads to hilarious misunderstandings.
Meanwhile, Raja's sister Neelam (Sheetal Joshi) sees local goon Ratanlal "Tiger" Pandey (Mukesh Rishi) who is the son of Ratan, killing an Inspector on the road and becomes a vital witness of the murder in court. Enraged, Tiger assaults and threatens her to not report his crime to the police. However, as a consequence, Tiger is badly beaten up by Raja, making him more vengeful against Raja and Neelam. To exact his revenge, he sends his henchman named Tommy (Shashi Kiran) to be the groom of Neelam but Raja and Rangeela find out his plan and marry Neelam to someone else. The court announces the death sentence to Tiger for the murder of the Inspector he shot earlier. Days pass, Neelam becomes pregnant, and she is admitted to a hospital for her delivery. Raja asks Prem to stay at the hospital as he is searching for money. Prem visits his father, ACP Malhotra. At the same time, Tiger escapes from jail to kidnap Neelam and recognizes ACP Malhotra, who shot his father Ratan and finds out that Raja is his son. He blackmails Raja to get ACP Malhotra to free Neelam. Raja, who does not know that ACP Malhotra is his real father goes to his house where Geeta also comes out from the paralysis by Raja's touch, and he comes to see the truth that they are his real parents and Prem is his twin brother. Finally, Raja and Prem come together to protect their father from Tiger. Raja finds out about his and prem's shared reflex, Nandu requests Raja to beat him so Prem would beat Tiger. And the story ends with the duo marrying their respective ladies.
