When Kevin Murdock, martial artist and outdoorsman extraordinaire, is revived from suspended animation aboard a transport pod, he and his nine fellow occupants have no idea what to expect. Murdock argues for caution after seeing something strange: animals also inhabit their new environment, all of them larger than their Earthly counterparts. Conflict soon erupts between Murdock and James Whittier - a politician with a lust for power and control. But soon, they all realize that there's something even more dangerous onboard, something that might cost them all their lives.
