As a haunting flashback unfolds, we encounter a young He, portrayed by Tony Leung Chiu Wai, huddled in a makeshift mine alongside fellow survivors, witnessing the tragic end of Guangzhou's fate in 1938. This formative event would propel him toward a formidable career, culminating in his role as the director of Shanghai's Political Security Department—a counterespionage division overseen by Officer Watanabe.
In the lead-up to the fateful bombing of Pearl Harbor in 1941, Director He consolidates his position within the regime, all while secretly collaborating with the Chinese Communist Party, alongside his wife, Ms. Chen, played by Xun Zhou. Their covert partnership revolves around providing vital intelligence to the underground network, ultimately aimed at dismantling Japanese occupation through espionage. Ms. Chen's guidance under her husband's watchful eye is symbolized through the pastries she discreetly sends him from a local bakery.
While Director He masquerades as a loyal agent of the Wang Jingwei regime, he diligently carries out assassinations, interrogations, and torture to garner the trust of Officer Watanabe. Watanabe's circle includes Minister Tang, played by Lei Huang, Captain Wang, and young officer Mr. Ye, depicted by Yibo Wang. Officer Watanabe, driven by ambition, believes that climbing the ranks of the puppet government is his ticket to power, yet he is always cautious of the true intentions of those around him.
Director He’s determination deepens when he covertly saves Ms. Jiang played by Shuying Jiang, a communist spy, from certain doom after her failed assassination attempt on Minister Tang. This action grants him access to invaluable intelligence about crucial Japanese figures, including a Japanese prince in military service. The repercussions of this knowledge will echo throughout his story.
The initial intent to negotiate peace between Japan and the Chiang regime suggests a redeployment of Japanese forces against the Soviet Union. This plan would inadvertently allow the Chiang regime to continue its battle against the Chinese Communist Party, effectively ceding control of Manchuria. Armed with newfound intelligence, the Chinese Communist Party launches a surprise strike, obliterating the Japanese prince and his aides during their final mission. This devastating turn of events not only disrupts negotiations but also fatally tarnishes Officer Watanabe's reputation.
Amid these crumbling alliances, the relationship between Mr. Ye and his dancer lover, Ms. Fang, played by Jingyi Zhang, faces a brutal severance due to Captain Wang’s treachery. The chilling news of Ms. Fang's murder by ideological adversaries shakes Mr. Ye's already fragile psyche, pushing him toward a blind fury against unsuspecting Japanese soldiers.
Officer Watanabe's growing suspicion regarding Director He’s true loyalties intensifies after discovering his tie to Minister Tang. This doubt leads Watanabe to manipulate Mr. Ye into becoming a pawn in his political tug-of-war.
The declaration of war against Great Britain and the United States following Pearl Harbor sends tremors of upheaval through Shanghai, now under Japanese military occupation. In this hostile environment, Mr. Ye finds himself increasingly entwined with Watanabe, who seeks to propel his own ambitions through Mr. Ye's unsuspecting assistance.
Mr. Zhang's desperate bid for freedom with Ms. Chen is thwarted after learning of her concealed marital ties. This shocking realization forces him to reevaluate his motivations, ultimately choosing to turn himself in to the Shanghai Political Security Department, unwittingly betraying the Chinese Communist Party. However, this act of betrayal would come back to haunt him at the hands of Director He.
In a stunning twist, Watanabe instructs Mr. Ye to eliminate the elusive Director He, culminating in a harrowing confrontation at Ms. Chen's apartment. In the aftermath, a bruised Mr. Ye presents himself to Watanabe with a report claiming that Director He has been apprehended and that Ms. Chen has paid with her life. This act earns him a promotion to Watanabe's secretary, along with crucial schematics detailing Japan's occupation of China through Manchuria.
As the narrative progresses, Mr. Ye and Watanabe shift their focus toward Manchuria, eager to explore new frontiers in both the political and military arenas, forever altering their paths.
As Director He inadvertently steps out of prison, cloaked in the guise of a political detainee, an unexpected sight greets him: Officer Watanabe and Mr. Ye, now constrained by the same fate as fellow inmates in a prison truck. The tension is thick as the two engage in a verbal sparring match, their animosity simmering just beneath the surface. In a cramped washroom, Watanabe expresses a crisis of confidence regarding the war, contemplating the possibility of a simpler life as a farmer, suggesting they could both seek absolution for their pasts. However, Mr. Ye silences him with a chilling stare, insinuating that Watanabe’s fate should rightfully be execution due to his role in the war.
Hidden behind this fragile façade, Mr. Ye's true alliances come to light; he has been serving as a double agent on behalf of the Chinese Communist Party under the guidance of Director He. The information provided by Watanabe turns out to be instrumental in ensuring the downfall of Manchuria. When the moment of treachery arises, Mr. Ye successfully dispatches Watanabe using Director He’s own weapon, an act that underscores the calculated nature of their subterfuge.
The film then leaps to 1946 Hong Kong, unveiling that Ms. Chen is indeed alive, living a quiet life alongside Director He and Mr. Ye. The trio seamlessly blends into the crowd, their pasts discarded like old secrets. Mr. Ye momentarily slips away, buying a cup of coffee for Ms. Chen at a charming café before visiting Captain Wang's family restaurant, where tales of escape and hope for their missing son linger in the air. Mr. Ye vanishes into the throng once again, all while visiting a nearby temple where Director He is found in prayer. Upon his return to Shanghai, Director He encounters the familiar sight of his wife’s bakery, a poignant reminder of the life they once had.
As the intricate narrative unfolds, it returns to Captain Wang, presenting an intimate moment with Mr. Ye that reveals shocking truths regarding Ms. Fang's death. Initially, Captain Wang's skepticism prompts him to raise his weapon toward Mr. Ye, a futile effort stemming from desperation to assert control. However, as he gazes down the barrel, he realizes that all bullets have been stealthily removed by Mr. Ye, rendering his defensive stance harmless.
This crucial shift in power dynamics exposes Captain Wang's vulnerability, as Mr. Ye's true commitment to the Chinese Communist Party emerges. The heartbreaking consequences of this revelation unfold swiftly, allowing Mr. Ye to exploit Captain Wang's moment of distraction and deliver the ultimate blow, leaving his fate enveloped in uncertainty.
In this pivotal segment, the film artfully orchestrates a series of events that meticulously unveil the ominous features of their treacherous world while highlighting the merciless pragmatism embodied by Mr. Ye. His calculating nature proves capable of extinguishing even the most resilient foes. This grisly outcome serves as a potent reminder that, in such a cutthroat landscape, perceived strength can dissolve rapidly in the presence of cunning and strategy.
