Donnie Yen returns as martial arts legend, Ip Man. Having defeated the best fighters of the Imperial Japanese army in occupied Shanghai, Ip Man and his family settle in post-war Hong Kong. Struggling to make a living, Master Ip opens a kung fu school to bring his celebrated art of Wing Chun to the troubled youth of Hong Kong. His growing reputation soon brings challenges from powerful enemies, including pre-eminent Hung Gar master, Hung Chun Nam (Sammo Hung). However, when corrupt colonial officials stage a life-or-death contest with formidable British boxer, Twister (Darren Shahlavi), to humiliate the Chinese people, the masters quickly forget their differences. Soon, the eyes of the nation are on the one man capable of securing a victory, Grandmaster Ip Man.
