Plot
Steve and the others help a giant named Kamber who has been shot by police, but he refuses medical help and has the humans instead contact a woman named Dr. Virella North. Once North arrives, it is revealed she and Kamber are part of terrorist plot to blow up half-a-million people. When she learns that the Little People have overheard the plan, she tries to kill them, but they manage to escape with Fitzhugh injuring his leg. Betty and Valerie stay with him while the others try figure out a clue left behind by Kamber that could lead to the location of the bombs. However, Inspector Kobick captures Betty and Fitzhugh and doesn't buy their story of the terror plot, leaving Steve and the others to foil the plan themselves.
