Yu-cheng chen

China, 1915. A secret and unequal treaty that would increase Japan's dominance over China is about to be signed unwillingly but not before external forces jump in to make sure it never happens. Therefore both the US and a small band of thieves and orphans (among them Lau Sek-Ming and Alexander Lo Rei) are ordered by their foster father (Zhang Feng-Yi) to track it down in Shanghai. Feeling an unease in terms of their involvement in high politics all of a sudden, it becomes clear there's a traitor in the group...

Brothers Fay and Fong arrive in Shanghai dreaming of a future. They end up in the Horng Men gang, and Fong is sentenced to prison while his brother rises through the ranks. On an undercover mission in rival gang, Fay is killed and his brother seeks revenge.
