In WW II-era occupied China, railroad porter Ma Yuan (Jackie Chan) covertly led a ragtag band of insurgents that regularly and efficiently pilfered from Japanese supply lines... but whom the invaders regarded as only a nuisance at best. That stood to change when Yuan vowed to finish a wounded soldier's mission, and lead his crew on a peril-filled assault upon a strategic bridge. Throwback thriller for Chan also stars Huang Zitao, Wang Kai, Darren Wang, Hiroyuki Ikeuchi.
