Alive and hiding in South America, the fiendish Nazi Dr. Josef Mengele (Peck) gathers a group of former colleagues for a horrifying project -- he wants to clone Hitler. Barry Kohler (Steve Guttenberg) gets wind of the project and informs famed Nazi hunter Ezra Lieberman (Olivier), but before he can relay the evidence, Kohler is killed.

Mengele continues his murderous plot, creating 94 young Hitlers and killing their fathers to simulate the madman's own boyhood. As Mengele moves closer to producing global terror, Lieberman alone must discover the terrifying extent of his plan and stop it.
