When Nick wakes up, he's in the tower of a medieval castle in the Alps. Seriously. That's the precise moment when the entire enterprise goes so over-the-top loony that you'll either go along with it for the entire insane ride or reject it roundly as a big bag of ludicrous. Nick is introduced to Adrien Joyce, the major domo henchman of Baron von Drax, CEO of the Grendel Corporation. Joyce isn't a moustache-twirling bad guy bent on torturing Nick into revealing where he hid the shaving cream can. Instead, he offers Nick a job, and in order to explain the job to him, he has to take him on a tour of the entire castle, which turns out to be a fairly sophisticated genetics lab where Grendel Corporation has been breeding some dinosaurs of their own design, cross-breeds that never existed in any era of nature with all sorts of custom modifications [...]
Nick is put in charge of training these five dinosaurs, X1 through X5, and the first thing he does is name them. "Any soldier worth his pay has a name to answer to, not a number," he says. So we are introduced to Achilles, Hector, Perseus, Orestes, and Spartacus, each of them a specially created deinonychus, which is sort of like a miniature T-rex. They have super-sensitive smell and hearing, incredible strength and speed and pack-hunting instincts, and they have modified forelegs, lengthened and topped with more dextrous fingers, as well as dog DNA for increased obedience and human DNA so they can solve problems well. All of this is topped off with a drug-regulating implant that can dose them with adrenaline or serotonin as the situation demands.
