Plot

Twin brothers who are separated soon after birth, meet in adulthood and join forces to defeat their common enemy, a notorious criminal.

Mrs. Malhotra's (Reema Lagoo) twin sons were separated at birth, so now she only has one son beside her. Since then she has been in shock and confined to a wheelchair in the USA. Quiet and mature Prem (Salman Khan), one of the twins, returns to India with his father Mr. Malhotra (Dalip Tahil) and mother Mrs. Malhotra to marry outgoing and precocious Mala (Karishma Kapoor), who is the daughter of Mr. Sharma (Kader Khan). There Prem meets his identical twin brother Raja (also Salman Khan) who is a thief and also exactly the opposite in nature to Prem. A series of comic scenes result as a result of the twins getting together. Raja loves quiet and mature Roopa (Rambha) and both the girls are confused by the change they perceive in their respective lovers. To muddy the waters Tiger Ratanlal (Mukesh Rishi) has sworn vengeance against the Malhotra family for what they did to his father (Deepak Shirke).—Soumitra

Jayantilal "Ratan" (Deepak Shirke) is a robber. Inspector SP Malhotra (Dalip Tahil) arrests him. Ratan is sentenced to death in court. Ratan attacks Malhotra outside the court and Malhotra shoots at his leg, injuring him. Ratan is taken to the hospital.

At the hospital, Malhotra is waiting for his wife Geeta (Reema Lagoo), who is in labor. She gives birth to twins. The twins were conjoint with a slight connection to each other in their arm. The doctor explains that the twins had to be separated with a minor operation and that both babies have a reflex action, which means that "what happens with one baby might be felt and reflected by another" depending on the proximity between them.

Ratan escapes after his operation and takes one of the twins with him as hostage, injuring Geeta. Malhotra goes after him, but unable to find his son, shoots escaping Ratan to stop him dead. Ratan had met his son Tiger, who sees Malhotra shooting at his father. Before dying, Ratan asks his son to avenge his death. Tiger's uncle takes Tiger away from a back door to escape the police attack.

The building where Ratan was hiding explodes (when a cache of grenades stored inside catches fire) and Malhotra thinks his kidnapped son is dead. but Ratan had already left Malhotra's son on the railway tracks. Now, when baby #1 rolls over in his crib, baby #2 rolls over on the tracks and is able to escape an oncoming train.

The kid grows up as Raja (Salman Khan) and finds a girl child on the steps of a local temple, whom he adopts as his sister. He finds another orphan, Rangeela (Shakti Kapoor) and becomes his friend. They both together take care of their sister Neelam and become thieves. They are arrested when Raja roughs up bullies in college who were harassing Neelam.

On the other hand, Geeta goes into depression and gets paralyzed. Malhotra takes her to the US for her treatment, where the other twin Prem (also Salman Khan) is brought up. He comes to India as a rock star for a show. He is received by Kishan Sharma Saab (Kader Khan) (Malhotra's friend) who wishes to marry his daughter Mala (Karisma Kapoor) to him. Prem likes women who embrace their Indian culture.

Raja had just escaped from jail giving the slip to policemen Vidyarthi (Anupam Kher) and Guru (Satish Shah). While Guru and Vidyarthi bicker about Vidyarthi taking undue credit for arresting Charles Sobraj, Raja and Rangeela escape in their jeep. Raja & Rangeela see a motorcyclist steal a money bag from Sharma Saab (which they themselves wanted to steal) and follow the motor cyclist to find out it was none other than Sharma Saab's daughter Mala.

Raja escapes with the money bag and later Mala figures out that her horoscope has her marrying a thief. She believes Raja is her man. Later she even starts assisting Raja in his petty robberies around the city and bailing him out of situations where he is about to be caught. Mala is in love with Raja. Vidyarthi and Guru continue to chase Raja and Rangeela. It is clear that even though Vidyarthi is the senior inspector, he cannot function without Guru's guidance,who is his partner and constant companion.

At the airport, Prem finds Roopa (Rambha), daughter of Sundari Batwani (Bindu), the organizer of his public shows in India. Roopa is rooted to her Indian cultural background and dresses appropriately, despite Sundari pushing her to dress more provocatively to lure the US based Prem. At the airport, Prem gets a reflex action from Raja (who was with Mala, and was kissing her in a garden), and ends up kissing Roopa and upsets her. Sharma brings Prem to his home.

Tony (Jack Gaud), Sundari's nephew also wishes to marry Roopa. Meanwhile, Mala misunderstands Prem for Raja and starts flirting with him at her house. One day, in a restaurant, both Twins see each other and find out that they are identical, which leads to hilarious misunderstandings. The police inspectors Guru and Vidhyarthi find Prem and Raja in a mall. Prem leaves with Roopa to her house, and Raja runs and hides in Sharma's house (who believes this is Prem and thus doesn't mind Raja flirting with Mala in from of him)

Meanwhile, Raja's sister Neelam (Sheetal Joshi) sees local goon Ratanlal Tiger (Mukesh Rishi) (son of Ratan), killing Guru on the road and becomes a key witness of the murder in court. Enraged Tiger molests her and Raja fights with him to save his sister. Vidyarthi is distraught at the loss of his trusted friend. Tiger, again to get his revenge from Raja, sends his henchman named Tommy (Shashi Kiran) as the groom of Neelam, but Raja finds out his plan and marries his sister to somebody else. The court announces the death sentence to Tiger for the murder of Inspector he shot earlier. Meanwhile Malhotra returns from the US and wants to marry Prem and Mala. But Prem refuses to marry Mala, which infuriates her. Eventually the girlfriends figure out that Prem and Raja are twins.

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 going in search of money, Prem visits his father Malhotra.

At the same time, Tiger escapes from jail to kidnap Neelam and recognizes Malhotra, who shot his father Ratan and finds out that Raja is his son. He blackmails Raja to get him Malhotra to free Neelam. Raja who doesn't know that Malhotra is his father goes to his house where Geeta also comes out from the paralysis by Raja's touch and he comes to know the truth that they are his parents.

Finally, Raja and Prem come together to protect their father from Tiger (Raja is locked in a cage and has to beat up Rangeela who in the same cage, so as to use reflex action in Prem (who is outside the case) to beat Tiger and his goons) and the story ends with the duo marrying their respective ladies.
