Dr. DeMarco (Wendell Corey), a disgraced scientist, is conducting bizarre experiments at his hidden laboratory. He seeks to create a race of superhuman zombies using the reanimated corpses of recently deceased individuals. DeMarco's ultimate goal is to build an army of unstoppable creatures that he can control and use for his sinister purposes.

Meanwhile, a team of intelligence agents led by Holman (John Carradine) and his associate Satana (Tura Satana) is investigating a series of gruesome murders that seem to have a connection to DeMarco's experiments. The victims show signs of having been killed by superhuman strength and advanced weaponry.

As the investigation progresses, the agents uncover DeMarco's diabolical plans and his connection to the creation of these "astro-zombies." They must find a way to stop him before his army of reanimated killers grows beyond control and wreaks havoc on the world.
