Many notable actors, including Jet Li and Donnie Yen, have portrayed Chen Zhen on screen after Bruce Lee.

Chen Zhen is believed to be based on Liu Zhensheng (劉振聲), an apprentice of Huo Yuanjia, a martial artist who lived during the late Qing dynasty of China.

After Huo Yuanjia meets his demise under dubious circumstances, Chen Zhen discovers that his shih-fu was poisoned by their rivals from a Japanese dojo in Hongkou District, Shanghai.

The furious apprentice seeks to bring the murderers to justice and embarks on a brutal quest to avenge Huo Yuanjia and revive his shih-fu's legacy, the "Jingwu Spirit".
