Nick Grainger, a young college student working on an archaeological dig in Egypt, accidentally activates a gate to a different universe. He, along with three of his companions, are thrown into the ancient alien gateway system between parallel worlds. Lost in the multiverse, they must search for a way home.

On their journey, their gateway opens into strange new worlds, similar to their Earth, but in different times and in places, where life has been changed by one simple event in the course of evolution. It is on one such Earth, they arrive in Egypt, not as it was in the days of the ancients. Now, it is a place where a technologically advanced race of gods rule.

Nick is claimed as a host for the god of death and the afterlife, Anubis. He and his friends flee through the gate, but Nick harbors a dark secret. Anubis still inhabits his body.

As the group travels through the multiverse, they begin a search for a possible way home, located in the fabled Atlantis.
