Scot is haunted by a pretty, female, former FBI agent, named Sharon, who insists he help her catch her killer. Scot does so and they strike up a unique partnership. Sharon helps Scot cheat gambling at cards in casinos. In turn, Sharon spies on killers, terrorists and human traffickers and gives Scot her Intel. Scot cooperates with certain state and federal law enforcement agencies along with the military to achieve justice and rescues victims.
. Scot and Sharon get sucked through the wormhole to another world. That world is some sort of science project created by the little grey aliens that visit Earth in saucer ships. The alien species, known as Greys, have used DNA from Earth and other worlds to bioengineer all kinds of different life forms on a very primitive planet. Monsters and humanoids of all types inhabit the planet, and Scot finds himself constantly chased with Sharon trying to keep him one step ahead of the dangers. They manage to find their way back to Earth eventually, but they discover during the brief period they were gone decades have passed on Earth and the planet's population is being fed on by astral vampires, that only Scot and a rare few psychics can see.
