Output: Nachiappan is a rich Indian restaurateur in Los Angeles, United States. His twin sons, Vishwanathan and Ramamoorthy, are senior medical students who help him out in the evenings alongside the restaurants chief cook, Juno. One evening, Vishwanathan goes to the airport to check on the familys supply concession and sees that some fellow Indians from Tamil Nadu – Madhumitha, her brother Madhesh, and their grandmother Krishnaveny – have difficulty with an address. He pitches in to help and learns that they just flew in from India so that Krishnaveny can undergo a crucial surgery to remove her brain tumour. Later at the hospital, Vishwanathan who is an intern at the same hospital visits Krishnavenys room after the operation, and notices she has been operated on the wrong side of her brain. Vishwanathan appeals aggressively to the doctors and has the error corrected by another surgery and then spearheads an angry fight for compensation. The hospital compensates 2 million to avoid a court case. Viswanathans drastic measures win the respect and love of Madhumitha and her family. When Krishnaveny realises that Vishwanathan and Madhumitha have fallen in love, she extends the familys stay in the United States and takes a liking to Vishwanathans good nature. However, Nachiappan objects to the budding romance and wants his sons to marry identical twins because he himself has an identical twin brother, Pechiappan who has slow memory. They both had married for love in their youth, but are now estranged because Pechiappans wife Sundaramba showed such tyrannical behaviour towards Nachiappans pregnant wife Meiyaththa, that the latter died delivering the twin boys. Krishnaveny tries to solve the problem by telling Nachiappan that Madhumitha also has an identical twin, Vaishnavi. The story fabricated by Krishnaveny is that Vaishnavi has been brought up in an orthodox Brahmin household. At this point they ring in Madhumithas alter ego, contrasting Madhumitha with a very demure, typically traditional Indian version. Nachiappan falls for the act and visits India along with his sons to meet Vaishnavi, unaware that Vaishnavi and Madhumitha are the same person. Meanwhile, Pechiappan arrives to a warm welcome by his brother, but later attempts suicide. Nachiappan then rescues him and comes to hear of his sad story and comes up with a plan. Accordingly, Nachiappan and Pechiappan switch places. Nachiappan goes to his brothers wife and impersonates her husband to convince and reunite with her through his sons Visu and Ramu marriage plan talks; he succeeds. Pechiappan impersonates his brother towards his nephews. Vishwanathan then meanwhile, discovers that Vaishnavi is Madhumitha and she was impersonating Vaishnavi. Enraged, he immediately leaves Madhumithas household along with his family, but Ramamoorthy persuades his father to have Madhumitha and Vishwanathan married. Though not knowing, it was not his father he talked critically about his uncle who was right there impersonating. That made him guilty. He decided to have Vishwanathan married to Madhumitha. When Nachiappan realises that Madhumitha does not have a twin, he goes and stops the wedding. There they figure out that the brothers impersonated each other as well to get along. Nachiappans brother Pechiappans wife Sundaramba persuades Nachiappan to have them married because Madhumitha did the same thing the brothers did. Eventually, Visu and Madhu get married followed by a grand dinner reception specially given by Madhesh.
