The United States Marines have been sold a new training simulator that's way beyond anything else available. It will allow Marines to train in specialized environments, without the cost associated with send the trainees to distant locations. The first trainee is sent into a simulation and returns. After he returns from the first test, he's tested for everything known to medical science. There's nothing medically wrong with the guy when he returns from the first test. The trainee is then sent into a simulation and he dies during the second simulation. Every trainee who's then sent into a simulation dies while he's in the simulation. There's nothing wrong with the trainee's body, except that it's dead. Into the mystery comes James Aquila. He's 18-years-old, six feet six inches in height, 240 pounds of lean muscle, with professional athlete vital signs. James is an ex-member of the SEAL Teams. For the kind of money they offer, James is willing to try the simulation. James is accepted as a trainee and sent into the simulator. It's not a simulator and James quickly discovers that he's in another world. There are aliens in the other world and the aliens want to kill him. James is an ex-member of the SEAL Teams, dismissed because of unusual tactics that he used during a mission and not because of inability to do a job, no matter who gets in the way. He manages to deal with the aliens and then encounters natives of the world to which he has been sent. Some of the natives of the world try to kill him. One of the natives who doesn't try to kill James is a girl named Pala. Pala is stranded on the tropical island where the non-simulation takes James. She is stranded because of a war between her Polynesian style tribe and another tribe. After several trips in and out of the simulator, James sets sail into an unknown world to try to get Pala home. In the process of the voyage to Pala's home, James encounters a group of aliens who call themselves Keegor. The simulator that brought James to the alien world is a Keegor space travel machine, stolen from the Keegor, and they want their device back. Well, the Keegor want their device back, but first they do have a few jobs for a James Aquila type guy.
