After mining complex ices deep in the Solar System, Jack Smith is concerned about his profit margin, but is it him who doesn't want to face quarantine or something squirming inside him? The Cryon Corporation Director, Geoffry Haven, is also concerned about the bottom line and might consider Jack an expense he can no longer afford, though perhaps suitable for a starring role in a snuff movie. Meanwhile, the human and unhuman agents of World Health must investigate. Perhaps it's time to deploy vat-grown killers and an anti-photon weapon, because the parasite is coming to Earth, and it's hungry.
