Heroic Duo

Ken Li's egocentric approach shapes his policing style. He rules with an iron fist and tolerates no mistakes, placing pressure on his underlings and Brenda. This attitude sets the tone for the tense, high-stakes investigation that follows.

Ken Li is tasked with investigating a rogue cop who has committed a crime. In interrogation, the officer claims he remembers nothing since meeting a mysterious man the night before, creating a puzzling memory gap. Li begins to suspect there is more to the case than a straightforward confession.

The investigation leads Li to Jack Lai, a master hypnotist who sits in jail for manslaughter after taking the rap for his wife’s duress. Lai clearly knows who is responsible and claims he can identify the culprit, but only if Li agrees to trust him. Li senses that Lai's mind holds the key to the case.

Li decides to risk freeing Jack, believing that only the hypnotist can reveal the real culprit. Jack agrees to cooperate, but warns that their alliance will be dangerous and unpredictable. The two set out together to unravel the conspiracy.

In their pursuit, they discover evidence in an apartment that reveals a plot to steal two Egyptian diamonds from Barry Lykin. The discovery ties the case to Ocean, a ruthless criminal mastermind. The stakes suddenly jump from a routine investigation to a high‑profile heist.

During a tense moment, Jack inadvertently hypnotizes Li, who then retrieves the diamonds from Lykin's safe. The act triggers a chaotic escape as Li is chased by Yeung, a fellow officer, through the parking area. The momentum shifts toward a dangerous confrontation.

As they reach the parking lot, Ocean's men ambush the police in a fierce shootout. Several officers are killed and Lykin is shot while escorting the diamonds, causing the diamonds to slip away into Ocean's hands. The operation collapses, signaling a deeper level of danger.

Jack hands the diamonds to Ocean, who uses his wife as a hostage to secure compliance. In the ensuing chaos, Li is arrested for the theft, complicating the pursuit and straining loyalties. The balance of power shifts as Ocean tightens his grip.

On the way to jail, the authorities use the situation to settle old scores, but Li escapes by leaping from the Tsing Ma Bridge. Brenda helps him vanish and rejoin the pursuit to recover the diamonds. The escape marks a turning point in Li's personal arc.

Brenda supports Li's flight and they chase Jack and Ocean through Hong Kong's streets. The partnership grows as they realize the mission isn't just about the diamonds but about their lives and loyalties. The team regroups to close in on Ocean's operation.

Ocean escalates by placing Jack's wife and the partner's children inside a vacuum chamber, aiming to force Jack's compliance. The clock ticks as the captives' oxygen depletes, heightening the stakes for all involved. Jack and Li race to find a way to halt the trap.

Jack returns to retrieve his wife and confront Ocean, meeting Li along the way. They split up to search the sprawling complex, using speed and stealth to outmaneuver guards. The plan hinges on timing and trust between the unlikely trio.

Jack locates his wife in the locked vacuum chamber while Brenda is seized by Ocean's men. Li finds himself cornered, forcing a stark choice between saving Brenda or stopping Ocean at the cost of personal risk. The moment tests Li's loyalties and resolve.

Li and Jack orchestrate an explosion that wipes out Ocean's operation. They retreat into a second vacuum chamber as oxygen cylinders detonate. Jack dies after laying his head on his wife's lap, a gesture that marks his ultimate sacrifice and love.

In the aftermath, Li realizes there is more to life than work and begins to treat Brenda with gentler care. The case closes with a personal rebirth for him, suggesting he will pursue a more balanced life.
