The story starts off with Raghu (Raghuvaran), a passport issuing officer, and his wife Shanthi (Shanthi Krishna). Raghu, being an honest guy, tells Shanthi that he cheated on her with a co-worker when he was in Goa. She immediately leaves for her mother's house. Raghu, being a transformed gentleman, tries to stop her by apologizing, but in vain. Raghu's brother Vijay (Vijay), being a good and supportive brother, and Shanthi's brother Suriya (Suriya), being a non-emotive but supporting brother, meet in a cinema theatre. Vijay, being a righteous brother, blames Shanthi to be the cause of the problem, and Suriya blames Raghu for the same. They keep on fighting at every chance. Meanwhile, both Vijay and Suriya find their own girlfriends and fall in love. One day Raghu finds a bundle of cash on his table and meets Muthukumaraswamy (Karan), the person who kept the money there. Raghu finds out that Muthukumaraswamy is an MLA, wanted by the police. Muthukumaraswamy wants to leave the country to escape from the police, and he needs a fake passport for flee the country, otherwise, the police will catch him. Since his passport is confiscated by the police, he tells Raghu to get one for him, but Raghu, being a sincere officer, disagrees and calls the police instead. Muthukumaraswamy gets angry and promises to avenge Raghu. Meanwhile, Raghu and Shanthi apply for a divorce.
Child custody of their daughter Sona (Nancy Jennifer), who was in Shanthi's sister's house when the breakup occurred, is given to the mother by the court. One day Suriya takes Sona to a fair and somehow loses her. In the confusion that follows, Sona falls from a Ferris wheel and is taken to the hospital by Vijay. She is brought to Raghu's house, once she recovers. Soon Vijay discovers that Sona has lost her hearing in the accident. Some days later Suriya finds that Sona is missing. Suriya finds Vijay and the two get into a huge brawl, then Raghu tells everyone that Sona is in his sister's house. Since Sona's custody is given to the mother, this action of Raghu's is wrong in the eyes of law.
So Shanthi and Suriya, accompanied by a lawyer, come to Raghu's house to get Sona back. At that time, Raghu suffers a serious asthma attack, while in the bathroom, and everyone saves him. After recovering, Raghu tells that Sona is not in his sister's house, but has been kidnapped by Muthukumaraswamy, who is out on bail. In the turn of events, Raghu issues a fake passport to Muthukumaraswamy, but he doesn't want him to escape from the police. The two heroes join hands, and make sure this doesn't happen. They save Sona, who is with Muthukumaraswamy's wife and brother-in-law in a van. Finally, the police arrest Muthukumaraswamy.
Initially, Vasanth roped in his lead hero from Aasai, Ajith Kumar and Vijay to play the lead roles though Ajith withdrew from the film eighteen days after production began as a result of date problems. The film was briefly reported to be titled Manasukkul Varalaama? (Can I Come into your Heart?) and also featured Swathi in the cast. Prabhu Deva was touted as a potential replacement to Ajith, though Vasanth then opted to replace Ajith with a debutant as he was able to commit under short notice. Vasanth then approached Suriya, son of veteran actor Sivakumar, to make his acting debut in the film. Vasanth had earlier unsuccessfully tried to persuade Suriya to star in his previous film, Aasai, in 1995 but the actor's father insisted that Suriya was finally ready to act. During the test shoot for the film, cinematographer K. V. Anand revealed that the team were worried how Suriya was going to stand opposite Vijay and that they made him wear two inch heels and made him put some shoulder pads. He added that for the first four days during the shoot in Kolkata, Suriya appeared to be uncomfortable in front of the camera and used to tell the team that he didn't want to do the film.
The film was the first Tamil project signed by Simran who was signed by Vasanth after he was impressed with her looks in Tere Mere Sapne, though Once More and VIP released earlier. Vasanth signed on Kausalya after seeing and being impressed with her picture at a jewellery shop and was unaware that she had already made her debut in the hit film Kaalamellam Kadhal Vaazhga.
The director revealed he had great difficulty in filming the song "Engengae", as crowds in Kolkata refused to co-operate with the technical team.
The film received mixed to positive reviews from critics. Ganesh Ramachandran, reviewer from Indolink praised the director for non-violent theme and applauding Raghuvaran, Vivek and Manivannan's acting which provide comedy relief. The music director Deva was appreciated for his "haunting numbers". On the other hand, the picturisation of the songs were criticized heavily. Karan Bali, writing for Upperstall, applauded the technical aspect of the film, K. V. Anand's cinematography, the script and Deva's music. Performance wise, Raghuvaran and Shanthi Krishna were said to be "reliably efficient as the brother and sister of Vijay and Suriya respectively", while the critic labelled the performance of Suriya as a "terribly awkward debut". The song "Manam Virumbuthey" was described as the best song in the film for its picturisation and choreography.
The film went on to win two Tamil Nadu State Film Awards for 1997 with the child artiste, Jennifer, securing the Best Child Star award for her performance. Harini also won the Best Female Playback Singer award for her rendition of "Manam Virumbuthae" in the album aged just 17.
The soundtrack consists of 6 songs, composed by Deva. All lyrics written by Vairamuthu.
