As Barry Kohler, a resolute young amateur Nazi hunter, secretly listens in on a covert gathering of Kameraden operatives in Paraguay, he unknowingly uncovers the dark plans devised by Josef Mengele, the notorious Auschwitz physician. With chilling precision, Mengele details the assassinations of 94 seemingly ordinary civil servants, all approximately 65 years old, scattered across Northern Europe and North America, all with a tight deadline set to unfold over the next two years. However, Kohler's harrowing discovery is abruptly cut short when he is brutally murdered by the Kameraden operatives while still on the line with Ezra Lieberman, a once-renowned yet jaded Nazi hunter.
Fueled by a combination of resolve and skepticism, Lieberman enlists the help of his savvy sister Esther, British journalist Sidney Beynon, and Jewish-American vigilante leader David Bennett to unravel the mystery surrounding the alarming deaths of civil servants who match Mengele's described profile. As they dig deeper into their investigation, they encounter a disturbing pattern: all the deceased men have sons, around 13 years old, who share strikingly similar features—pale skin, dark hair, and piercing blue eyes. Lieberman's quest reveals a tangled web of illegal adoptions orchestrated by Kameraden member Frieda Maloney, who is now incarcerated, and the shocking truth that these boys were funneled through a Brazilian intermediary.
Maloney’s cryptic hint regarding Henry Wheelock, who traded his newborn puppy for a baby boy, sends Lieberman on a compelling search to uncover the connection behind the boys' uncanny resemblances. Consulting biologist Dr. Bruckner, he learns about cloning, leading to a shocking realization: these boys are clones of Adolf Hitler, all genetically constructed from the very same DNA sample by Mengele. This sinister Nazi plot aims to recreate Hitler’s formative years by placing the boys with parents who resemble Alois (Hitler's abusive father) and Klara (his loving mother). The calculated murders of their fathers serve as a chilling replica of Alois' own demise when young Adolf was just thirteen.
With Maloney's puppy now an unintended linchpin to unraveling the mystery, Lieberman connects the dots of this nefarious scheme. Time becomes a critical factor when he discovers that Henry Wheelock is marked for execution in only four days, precipitating a frantic race to thwart the next phase of Mengele's malevolent design.
As turmoil surges within the Kameraden leadership, they scramble to halt the project amid worries about Lieberman's persistent inquiry and Mengele's increasingly erratic behavior—a man so unhinged that he violently attacks one of his own for a trivial error. However, Mengele cunningly evades those trying to stop his vile plans.
In the picturesque rural landscape of Pennsylvania, Lieberman arrives at the Wheelock home bearing distressing news, only to find that Henry has already fallen prey to Mengele's treachery. Masquerading as Lieberman, the doctor delivers the fatal assault before brutally shooting the investigator himself, leaving him gravely injured. To add insult to injury, Mengele finds himself cornered by a pack of ferocious Doberman Pinschers, their feral anger ignited by a profound fear instilled by the very man they now confront—Mengele, who bears an irrational dread of dogs.
As Lieberman battles to heal from his wounds, he fortuitously retrieves a crucial list from Mengele's pocket, detailing the identities of all 94 clones. However, his recovery is short-lived, as the consequences of blood loss take their toll, rendering him weak. During a subsequent hospital visit, Bennett presents Lieberman with an enticing proposal: deliver the list to allow his vigilante group to eliminate the clones. Unwilling to comply, Lieberman chooses instead to destroy the incriminating evidence, convinced that these innocent children may ultimately grow into harmless individuals.
The film closes on a chilling note as Bobby Wheelock, still grappling with the horrors he's witnessed, stares with unsettling intrigue at images of Mengele's mangled remains—a gruesome token of the monstrous acts committed by this infamous figure.
