Vaazhthugal is unique in that it is completely in Tamil without any English or other foreign words anywhere in the movie. This film tells the story of a young man named Kathiravan, the manager of a software company. When his best friend’s parents force their daughter-in-law out of the house, he decides to get married to keep his own parents happy. While interviewing a woman named Kayal to work for him, he falls in love with her and attempts to win her love. Kayal’s family, especially her grandfather, does not put faith in a marriage based on love alone, however.
