Beth and Lisa lived with their parents on the space station, Silver Flag. Silver Flag was a small space station, with a crew of 100 people. Beth was fifteen years old, with black hair and blue eyes, while Lisa was three years old, with blond hair and brown eyes. Beth and Lisa's mother was a docter, while their father was in charge of Silver Flag. Beth and Lisa spent most of their time on the promenade, watching the passengers as they wandered from one shop to the next. They did not know that a passenger on the spaceship, Star Fire, which had just docked at the space station, had contracted a highly contagious disease, when she visited a planet in the next solar system. The doctor aboard Star Fire had tried to contain the disease, by confining the woman to her cabin as soon as the woman started showing the symtoms of the disease, but by then it had spread all over the ship.

Beth, Lisa and the other children crawled through the hole, into the room. The cat was waiting for them in the room on the other side of the wall. "Why are you following me," the cat rumbled at Lisa, Beth and the other children. "We have never seen anybody like you before," Lisa said. The cat walked forward and sniffed at Lisa and Beth, before sniffing at the other children. The cat backed away from them in surprise. "You are just children," it said, in a female voice.
