Plot
Tom, Hal, Karen, Anthony, Dai and Margaret watch as kids with harnesses collect scrap metal for the aliens. Tom sees his son, Ben and the group prepare to grab him. Karen accidentally knocks a loose piece of rock from the building, alerting the aliens and the group runs away.
Back at the school, parents of harnessed kids come over and ask Tom if he saw anything. Mike tells them to back off as more and more badger Tom for the information. Col. Porter tells Tom that a doctor has a theory on how to remove the harnesses and that he wants to test it on Ben. Porter then tells him to bring Ben back safely. Tom meets up with Matt who heard that when a harness is removed, the kids die. Tom reassures his son that Ben will be fine.
