Filmed at the Wing Fong Farm in Ontario, this documentary follows the tilling, planting and harvesting of Asian vegetables destined for Chinese markets and restaurants. On 80 acres of land, Lau King-Fai, her son and a half-dozen migrant Mexican workers care for the plants. For Yeung Kwan, her son, the farm represents personal and financial independence. For his mother, it is an oasis of peace. For the Mexican workers, it provides jobs that help support their children back home.
