Felix Wong Yat-Wah

An illegal immigrant from Mainland China sneaks into the corrupt British-colonized Hong Kong in 1963, transforming himself into a ruthless drug lord.

When a terrorist who specializes in explosives takes hold of an underground tunnel, he threatens to kill hostages if his demands are not met.

After his attempted robbery runs aground, a thief takes a shine to his would-be victim, a charming prostitute, who begins to tell him her life story.
