Chomjan sells pickled fish using her family's secret recipe to support her sister Methinee's education abroad. With the help of Gloy, an orphan who treats her like family, she works hard to make ends meet. When Methinee returns, she brings a boyfriend from a wealthy background and, ashamed of her roots, asks Chomjan to lie about her job. The request deeply hurts Chomjan, who has sacrificed so much for her.
