Nachiappan is a wealthy and successful Indian American restaurateur based in Los Angeles. He has two sons – Viswanathan "Visu" and Ramamoorthy "Ramu" – who are identical twins. They both are medical students and spend their evenings helping out their father alongside the restaurant's chief cook, Juno. One evening, when Visu & Ramu go to the airport to do their lunch supply, Visu sees an Indian Tamil family from Chennai – Madhumitha "Madhu", her younger brother Madhesh, and their grandmother Krishnaveny – having some problems with the immigration authorities. Visu pitches in to help and learns that they just flew in from India so that Krishnaveny can undergo a surgery to remove her brain tumour. After many confusions, the trio meets with Ramu also. The twins arrange for the three to reach their host.
