Set against the background of Petaling Street in 1908, Petaling Street Warriors tells the story of a pair of married couple, Shi Duyao (Mark Lee) and Zhung Lichun (Yeo Yann Yann), who operate a Hokkien mee stall in Petaling Street, where they suffer from the inefficiency of the colonial government and suppression by the Chinese gangsters. While trying to impress his wife, Duyao encounters a mysterious yet strikingly beautiful kungfu expert, Xiaoju (Chris Tong), who claims that Duyao is a descendant of the missing Emperor Jianwen of the Ming Dynasty. To stop a group of Qing warriors and Japanese ninjas from robbing a treasure map that Duyao doesn’t even know he has, Lichun and her cousin, Liu Kun (Namewee), finally reveal their kungfu, turning Petaling Street into the ultimate battleground. Facing enemies of unthinkable powers, could Duyao unravel the mystery of his real identity and come to his wife’s rescue just in time?
