Mina’s village life seems peaceful as ever, but subtle environmental changes begin to affect everyday life. One evening, her family falls ill after eating fish from the polluted river, suffering food poisoning. Later that night, a heavy rainstorm drenches the village, causing river water to flood into the well. While taking medicine, they drink the unboiled well water, which worsens their condition. After learning the causes of their illness, Mina decides to improve the village’s environment.
