This story takes place on Mars, which is used as a quarantine for people with deadly illnesses. One day, the planet is visited by a young man of eighteen who has the ability to perform thought transference and telepathy. The exiles on the planet are thrilled with his ability and a violent fight breaks out over who will get to spend the most time with their visitor and enjoy the illusionary paradises he can transmit. In the struggle, the young man is killed and the escape he provided is lost forever.
