Sri Badrinatha Moorthy aka "Badri" is a happy-go-lucky youth who spends his days roaming around with his friends Azhagu, Howrah and Joot, ogling girls and repeatedly failing his exams. His father Viswanathan, a cafe owner, is disgusted with his irresponsibility and constantly chides him. His older brother Vetri, who is a college-level kickboxer and Viswanathan's favourite son, on the other hand, dotes on him. Janaki aka "Janu", who is Badri's neighbour and childhood friend, is in love with him, but the feeling is one-sided as Badri mainly considers her as a source of money and cars; Badri constantly borrows large amounts of money from Janu as well as expensive cars from her father's garage to impress girls.
