King of Hawkers centres around Zhang Nala (Dawn), who returns to Singapore from Hong Kong to restart her life at her family-run bak chor mee stall after divorcing her rich playboy husband (Collin Chee). Operating next to Nala's stall are others selling local cuisines, such as Ah Lau's Cantonese Cuisine, run by Liu Derong (Hugo) and Bestest Indian Food, which is operated by Raja (Das DD). When a multinational company organises a competition in an attempt to buy over Nala and other hawkers' recipes and businesses, they work together to retain their legacy.
