A reluctant Martian soldier is forced to join the army as they prepare to invade Earth. However, when they arrive, they are welcomed by a world at peace, full of people who are curious rather than aggressive. The protagonist meets a movie director, and it becomes clear that the people of Earth have planned to exploit the Martians for financial gain. He tries to escape back to Mars, but is run over by a car and killed.
