Oru Naal Koothu is a 2016 Tamil romantic comedy movie starring Dinesh, Miya, Nivetha Pethuraj, Riythvika and others. The story revolves around many characters who all share a common problem - marriage. One of the characters named Raj (Dinesh) has a problem with his lover Kavya (Nivetha Pethuraj) who is about to get married to another guy. Then we have Lakshmi (Miya George) who's father rejects every proposal that she gets by giving one or the other reasons - and this is happening for over 7 years! Then we have Susheela (Riythvika) whose guy Bhaskar (whom she is already engaged to) calls off the marriage citing a casual reason! Whether these characters will be able to resolve their marriage problems and get their life back on track forms the rest of the story.
