Upon returning to the Xindi weapon test site, the crew of Enterprise detects a Xindi ship in the area. They attack and board the ship, taking its occupants prisoner. Among the prisoners is Degra, the Xindi-Humanoid who is also the mastermind behind the superweapon. Unfortunately, the Xindi ship's databanks have been mostly erased and Degra and his men are less than helpful. Phlox, however, has discovered an interesting wrinkle in Xindi neurophysiology - it's possible to erase their most recent memories. Archer formulates a plan that involves Phlox erasing Degra's memories and Trip building a small mock shuttlecraft that will be housed on Enterprise.
