Complete story — includes the ending
The Skins make all the humans in Roswell, New Mexico disappear, turning it into a ghost town. Maria and Liz manage to slip through the cracks and don't disappear with the rest of the humans because they were out of town at the time. Upon returning to Roswell, they realize everyone is gone and freak out. When they get to the Crashdown, they meet up with the four aliens and together they try to figure out who is behind the disappearances. The Skins assault ends with the death of one of the aliens, Courtney. Fortunately Tess uses her mind blowing powers and destroys all the other Skins or so it seems until Max and Tess spot a boy resembling Nicholas on a scooter at the end of the episode.
