Harry Bittering and his family are among the first thousand Earthmen to move to Mars for the purpose of colonizing it. Yet Bittering feels out of place in his new home. His uneasiness is so profound that he wants his family to return with him to Earth. He has decided that Mars is meant to be inhabited only by Martians.
At the point when they show up by means of rocketship, in any case, Harry rapidly feels that something isn't right with the Martian climate, and that it is as of now working slow and slippery changes upon his family. Harry Bittering and his family move from Earth to Mars to partake in another settlement. His family convinces him that they should move also, and they give up the vast majority of their assets them as they do as such. In spite of the fact that they proceed into town and set up an agreeable way of life in the new settlement, Harry can't shake the inclination that something isn't right. They're frightened to understand that the settlement has been deserted, and botch the old pioneers, who have totally failed to remember their inceptions, for local Martians. At the point when he and his family in the end get back to town, Harry loses steam on his rocket project, seeing it with less eagerness than previously. After five years, men from Earth show up declaring that they've won the conflict. Considerably really disturbing, the actual qualities of the pioneers are transforming: they are getting taller, with brown complexion and brilliant eyes more fit to the Martian climate While Harry is alarmed by this, different pilgrims are, once more, less troubled.
