Dr. Don Blake is an American physician vacation in Europe when he over hears an old man telling people of stone men from outer space. They of course think he is nuts, but Dr. Blake believes him and decides to have a look for himself.

These stone men come from the planet Saturn and have increased strength and invulnerability thanks to Earth's atmosphere. Dr. Blake overhears the stone men speaking about killing any who discover them and flees. He arrives at a cave unable to find another exit and concedes defeat. Dr. Blake leans back against a wall revealing a hidden door, behind which he finds a very old walking stick, which he tries to use as a lever to move a boulder blocking a secondary exit from the cave. In frustration he strikes the boulder with the cane producing a blinding light and transforming himself into Thor.

As Thor, Dr. Blake is easily able to move the boulder and escape the cave. Outside he tests his abilities based on what he had read about Norse mythology. He hen he lets go of the hammer for more than 60 seconds, he returns to his normal self. He tests the hammer's ability to return to him when thrown, throwing it through a tree, summons storms, and stops them before hitting the hammer on the ground once to return himself to normal and the hammer back into a walking stick.

At that time the remainder of the stone men attack fleet enter the atmosphere and are picked up by military radar. The stone men's ships are protected so that the missiles cannot harm them. Seeing this, Dr. Blake transforms back into Thor and hurls himself with his hammer in the middle of the landing party. The stone men cannot match strength with Thor and his hammer and are quickly defeated.

Thinking that all humans are like Thor, the stone men flee the planet. As soldiers arrive to the scene, Thor transforms back into Dr. Blake and is able to walk away without anyone taking a second look.
