His parents are missing, and are working with Bucky's nemesis Dr. Tanner on some kind of youth-restoration project. Bucky wants the duo to help him. They go to Tanner's spa and discover that the youth-project has gone awry. Bucky's parents, and most of the customers, have become children, while other customers have become devolved apemen. Tanner' knocks out Zeta and forces Bucky to work for him to try and reverse the process. Bucky and Roe manage to escape, as does Zeta. An explosion triggers the nearby mud-geysers, destroying the complex.
