Chinese Australian Kim Chen is a descendant of one of the first Chinese immigrants to Western Australia in the 1880s. On the banks of the Swan River in Perth she continues her father's legacy of operating a Chinese urban farm. She has a son, Ayden, born to her first love, Jack, the boy next door who has left her to work as a war photographer in Afghanistan. Kim struggles to keep her farm profitable. With the assistance of the Immigration Department, she enlists the help of Ara, an Afghan refugee awaiting release into the community. Kim's dream is to develop a world garden, a garden that encompasses plants from the countries of all the migrants who have settled in Perth, and create a self-sustaining business from the produce. She faces opposition from her competitors, her neighbours, and eventually must fight to save her identity, her son and her land.
