A bomb explodes in a park in Taipei but nobody is hurt. The explosion results in a downpour of rice onto the grass. One of the spectators is a Yang Rumen, known as Ru. This young man comes from a farming family and has first hand experience of how the situation for farmers in Taiwan has steadily worsened ever since the government eased import regulations for agricultural products in the late eighties. After 2002, when Taiwan joins the World Trade Organization, local farmers are even told to let their fields lie fallow and transform them into lakes. In the meantime, Ru decides to become the voice of these farmers and remind the government of its obligations. Courageous farmer Yang Rumen becomes the "rice bomber" and a hero in his native Taiwan.
