After returning to New York, Rick Jones finds a job and a place at the Minos Tower, owned by sociologist Cornelius Webb. What seemed to be a paradise location first gets weird when tenants, Rick included, start having visions of enormous rats and bats in the midst. Then, smoke, fire, floods, walls that move, menace everyone who runs for their lives, without being able to escape the edifice.
Rick summons Captain Marvel on time to help, but even his alien powers cannot counter the attacks... orchestrated by Webb himself. He’s running an experiment to prove that under certain extreme conditions, humans behave like animals. The book he will write with his findings would bring him a fortune, or so he thinks.
Mar-Vell tries stopping Webb at his lair, but he’s captured by an atomic force field. Unnoticed, Mr. Weiss, a tenant who the hero saved minutes ago, and a Jewish survivor from Nazi camps, enters the lair, and attacks Webb, who resembles him of a dictator. Weiss short circuits the major computer, causing an explosion that destroys the place.
Rick Jones wakes up amid debris. Unfortunately, Mr. Weiss didn’t make it. Webb finds himself alone, puzzled because his experiment and theory are ruined.
