Enterprise: Doctor's Orders

When the Enterprise tries to travel through a deadly area of the Expanse, Dr Phlox gets the go ahead by Archer to put everyone into temporary comas so that no one is impacted during the transit. The attempt proves more perilous than originally thought, and not only does Phlox find himself needed to guide them out of the rapidly-growing area, he also finds himself hampered by hallucinations brought on by the trip.
