Intrigue

Brad Dunham was dishonorably discharged after Tamara Baranoff testified against him. Marc Andrews reveals this secret to Brad moments before dying, Tamara's testimony was responsible for Brad's unjust court-martial, which forced him out of the military and into the dangerous world of post-war smuggling in Shanghai.

Tamara wants Marc dead because he is an American journalist investigating her black market operation in Shanghai. She orders Brad to stop Marc's investigation, warning him to stay away from the reporter. When Marc gets too close to exposing the criminal ring, Tamara's rival kills him to prevent the story from being published.

Tamara is killed during Ramon's ambush of Brad at the climax of the film. Ramon, the former associate whom Tamara fired to appease Brad, attempts to shoot Brad but his gun misfires, causing the bullet to strike Tamara instead. She dies as a result of this accidental shooting.

Tamara fires Ramon earlier in the film, creating the motive for his later betrayal and attack.

Brad turns against Tamara after Marc Andrews dies in his arms. The dying reporter asks Brad to deliver his exposé story and reveals that Tamara's testimony caused Brad's unjust court-martial. Witnessing his friend's murder and learning of Tamara's betrayal motivates Brad to dismantle the black market operation she controls.

After deciding to expose Tamara's operation, Brad begins distributing the smuggled goods to needy citizens in Shanghai. This act represents his moral transformation, he uses the illegally obtained merchandise for humanitarian purposes rather than profiting from crime, showing his shift from selfish smuggler to righteous exposer of the black market.

Marc Andrews is killed by Tamara's rival in the black market operation. As Marc attempts to deliver his story exposing the criminal network, Tamara's rival attacks him with a knife, stabbing him. Marc dies shortly after reaching Brad and revealing Tamara's role in his court-martial.

Before dying, Marc Andrews reveals two critical pieces of information to Brad. First, he asks Brad to deliver his expos exposé story to the authorities. Second, he tells Brad that it was Tamara Baranoff's testimony that led to his unjust court-martial from the Army Air Corps, revealing Tamara as the architect of Brad's downfall.

Tamara fires Ramon Perez to appease Brad Dunham after Brad demands a 50% cut of the black market operation. When Brad steals back his cargo to force higher payments, Tamara chooses to side with Brad over her longtime associate Ramon. She dismisses Ramon as a show of good faith to secure Brad's continued involvement in the smuggling operation.

Brad meets Linda Arnold, a social worker operating in Shanghai, during his time in the city. Their friendship develops as Brad is drawn to her genuine character and humanitarian work. This connection makes Tamara jealous and serves as a catalyst for Brad's eventual moral awakening, as Linda represents the honest life Brad has been missing.

By the film's conclusion, Tamara's black market operation collapses. Brad distributes her goods to needy citizens, undermining the criminal enterprise. After Tamara is accidentally killed during Ramon's failed ambush, Ramon is arrested, and the key players in the operation are neutralized, effectively ending the crime ring.

After being dishonorably discharged from the Army Air Corps, Brad Dunham turns to smuggling as a means of survival in post-war Shanghai. He uses his piloting skills to fly smuggled goods into China, quickly thriving in the black market despite the moral compromises. His initial motivation appears to be financial gain, though his character evolves throughout the film.
