Imagine if you were taken right now from wherever you are on Earth to another planet filled with dangerous creatures and aliens. What would you do? How would you get home? That's what happens to four people from Earth (a shy librarian, a tough cop, an arrogant businessman, and a geeky teen girl) who are transported an alien world, and the only way home is to make their way through a maze that crosses thousands of planets throughout the Galaxy. They'll have to work together to uncover the secrets and survive the dangers of NEXUS.
