Raghu, a software engineer, faces several challenges in his arranged marriage as he suffers from erectile dysfunction and tries to find a solution to his problem.

Sunderrajan aka Sura (Shiva) comes to Chennai from Coimbatore on his way to Saudi Arabia. He is received by Marthandam (S. P. B. Charan), a veterinary doctor who is going to marry his sister soon. After the travel agent informs Sura that he cannot taste liquor or women in Saudi, he and Marthandam go to a wine shop to have the last gulp. It is a dry day thanks to elections. Sura is determined to taste the ‘quarter’ and starts his journey to various places in Chennai where he is told that liquor would be available. He goes to a politico who supplies wine for votes, a star hotel, an Anglo-Indian group of youngsters, a fish market, a gambling den, a kulfi shop, and a brothel house, among other places, all in search of ‘quarter’. During his trip, he meets Saraswathi aka Saro (Lekha Washington), who attempts suicide after her parents scold her, and King-Prince, a father-son duo (both roles played by John Vijay) who runs a gambling center. How Sura, in the company of Marthandam and Saro, succeeds in his mission and leaves for Saudi forms the remaining story.
