Five police officers in Hong Kong are kidnapped. The police commissioner is on a business trip overseas. Two vice commissioners, Sean Rau and M.B. Lee, then take over the case. The two vice commissioners are rivals who both vie for the police commissioner seat. At first, M.B. Lee takes the lead in the case, but comes to a dead end. Sean Lau then takes the lead, but he falls into a trap. Both men are then investigated by the ICAC (Independent Commission Against Corruption).

A suspected criminal mastermind escapes from police custody, throwing the city into turmoil. With the police department now divided, rival police chiefs are forced to take their fight to the streets of Hong Kong with deadly consequences.

Flashback to 1994, before Hong Kong’s handover to China. As the Special Branch of the Royal Hong Kong Police Force prepares to disband, the kidnapping of a powerful business tycoon ignites a dangerous covert power struggle within the force. Caught in the conflict are two officers: the passionate and righteous M.B. Lee and the cold-blooded and ambitious Peter Choi. Four formidable factions — the city’s wealthiest family, the Poon’s, the police, the triads, and the British authorities — are drawn into a deadly vortex of ambition, betrayal, and hidden agendas. As old alliances fracture and new ones form, Hong Kong stands on the brink of a seismic power reshuffle that will cast a long shadow into the future.
