Working on the New York to Bangkok inter-dimensional link, a technician is killed by energy-eating creatures. Liam and Augur suspect the creatures may be from another dimension, and will drain every energy source on earth. The mothership becomes infested with the creatures, leading the Taelons to put themselves into a near-death state to protect themselves.

After a Jaridian energy beam turns several Taelon companion protectors into assassins, Zo'or demands that they be turned over to him in 24 hours - or he will open fire on Earth. Da'an, meanwhile, dispatches Liam to take the assailants alive; and Sandoval becomes a pawn of the Jaridians.
