The Bittering family lands on Mars. They came to Mars to escape a war that was happening on earth.
Laura (the dauter) told her parents that over the radio she heard that an atomic bomb hit new york and all of the ships were destroyed so they were stranded on Mars.
Mr. Bittering tells his wife that the Martian soil is changing their plants and food. For example making the grass purple and making the roses green.
What Mr. Bittering warned about came, they changed. They became taller, darker, skinnier, and had yellow eyes.
All of the Earth people have now turned into a martian and forgotten their past life. They no longer speak English and have moved into the martian villas, they are no longer human.
Five years later the captain and some lutenists came to rescue the people who were stranded on Mars and came to tell that that they won the war. When they got to Mars they found the human villig abandon so thay set up base in an abandoned bar. When the lutenit came back he told that captin that all he found were Martians and that they didn't know anything about the humans.
