Dhayalan (Samuthirakani), Singaperumal (Thambi Ramaiah) and Nadunilayan (Namo Narayana) live in the same community in a town near Neyveli, Tamil Nadu. They are expecting the arrival of their respective children and they all have different perspectives on child-rearing. Dhayalan makes his wife go for a traditional delivery at home, while Singaperumal instructs the doctor to perform a C-section on a scheduled date and time, for his child to have the best possible horoscope, pre-calculated based on the date and time of birth. All three of them have baby boys. Dhayalan names his son Vetriswaran, Singaperumal names his son Chakravarthy, and Nadunilayan names his son Mayilvaganam.
