It's a story about a diplomat-turned farmer Ms. Zhang who's leading a one-woman crusade to implement her philosophy of sustainable farming. She’s transformed a chemical-polluted area into an organic farmland, and supported it by selling the land produce to city consumers. Will her initiative become sustainable and provide a possible solution for other heavily pesticide-and-fertilizer-polluted farmlands in China? Following her story, the film explores the endangered Chinese food system, and observes the dilemma in land use and food consumption. It also reflects on the low social status and low economic income of Chinese farmers. Will the sustainable farming be the hope of change for them too?

本片通過講述四個人物的故事，試圖展現更大的圖景：張大姐曾經是一名常駐國外的外交人員，十幾年前她卻放棄令人艷羨的職業，來到農村成為一名農民，只為了「得到安全的食物」；天樂曾經是記者，如今卻在擺攤賣菜，只為了幫助採用生態方式種植的小農戶；姜阿姨的退休生活並不富裕，卻是生態農產品堅定的支持者，哪怕價格比平均水準高出3倍以上；李大姐是普通農民，白天在有機農莊打工賺錢，晚上卻回到自家的口糧田噴農藥，她不是不知道其中危害，只是沒有選擇……這幾個人物因為共同的主題–食物–而聯繫在一起產生交集，他們面對的困難和挑戰，在某種程度上講，也是這個國家所面對的。
