The story revolves around Kaali, a brash, money-minded, who is a Shylock of sorts when it comes to ensuring that the people who she had done the Seimurai return the favor, and her sister-in-law Meenakshi, who has become the subject of her taunts for her inability to do so. Egged on by a fractious relative, Kaali’s husband Maayan had given a huge amount as seimurai for his sister Meenakshi’s family event, and unable to do the same, her husband had ended his life.
Twenty years later, with a son, who is a wastrel, can Meenakshi regain her dignity when Kaali organizes a seimurai to arrange the wedding of her daughter Amuthavalli?
