Yes, Madam!

Inspector Ng intervenes as criminals attempt an armored car robbery in Hong Kong and halts the heist. The confrontation ends with the thieves fleeing and the scene secured by the police. Ng's decisive action sets the stage for a broader investigation into the criminal network.

In another part of the city, a deal between a Westerner and an assassin goes sour and ends abruptly. The assassin kills the Westerner, removing a key intermediary who unknowingly held critical microfilm. The violent turnover draws Ng and other investigators into the wider case.

Asprin and Strepsil slip into the crowd to pickpocket the dead Westerner and steal his passport. They cash in on the confusion created by the murder, tying their fate to the hidden microfilm. Their actions pull them deeper into the network.

Inspector Ng learns the dead Westerner is Richard Nornen, with whom she had been romantically involved. The revelation exposes Nornen's undercover work and heightens Ng's personal stake in the investigation. The emotional cost of the case becomes apparent.

Authorities reveal Nornen's undercover status and that the microfilm is missing. Carrie Morris from Scotland Yard arrives to help Ng recover the microfilm and bring the criminals to justice.

The microfilm ends up in the hands of petty thieves, complicating the pursuit. The police focus on using it to prove Mr. Tin's involvement in the criminal network.

Asprin and Strepsil return the stolen passport to Panadol, maintaining their tenuous grip on the larger scheme. Panadol's links in the criminal chain become clearer. The passport remains a critical asset in the operation.

Panadol sells the passport to a criminal who tries to flee the country. Carrie Morris intercepts the buyer at the airport and halts the escape. Ng allows the suspect to depart but not by plane, ensuring the pursuit continues on the ground.

While in custody, Panadol mentions Asprin and Strepsil as accomplices, widening Ng and Morris's investigative net. The authorities realize there are more players in the network than they initially thought.

Tin escalates the pursuit by sending three thugs to seize the microfilm from Asprin and Strepsil. Strepsil, overwhelmed by the threat, hands over the microfilm to the thugs. The microfilm's fate hangs in the balance.

Ng and Morris attempt to arrest Tin for possession of the microfilm, but Tin's copy is Panadol's fake. The evidence collapses, and Tin escapes immediate capture. The pursuit intensifies as the truth about the microfilm's origin deepens.

Tin's thugs locate Panadol and beat him so severely that he dies. His death removes a crucial source of information about the microfilm and the network. The investigation loses a key link just as pressure mounts.

Asprin and Strepsil arrive at Tin's house with Ng and Morris in close pursuit for a final confrontation. A fierce battle erupts and the microfilm is destroyed in the chaos. Ng and Morris are arrested for trespassing during the raid.

News of Panadol's death fuels Asprin's rage, and he grabs a police officer's gun. He shoots Tin to death just as Tin is about to walk free because the evidence is destroyed. The killing marks a bloody turn in the case.
