Set in the 1980s, the film depicts cut-throat machinations between Hong Kong’s jostling business elites amidst the backdrop of the tail end of British colonial rule. It tells the story of the rise and bust of a fictional Hong Kong company called Jiali Group, following the travails of its chairman Cheng Yiyan through 15 years of investigations by the Independent Commission Against Corruption as murders are committed, billions in market value evaporate and millions are spent on litigation fees.
