In a burst of alien energy, Sky suddenly grows from an infant to a girl in the early stages of adolescence. Miss Meyers orders Sky to destroy the Metalkind and fulfill her destiny as a genetically-engineered weapon, but Sarah puts a stop to those instructions and makes a quick escape with her friends. Miss Meyers rigs up her Metalkind captive to send a distress signal to others of his kind, drawing them to Earth. At Sarah’s home, Mr. Smith finds that Sky’s destructive abilities can’t be deactivated: if she ever encounters sufficient numbers of Metalkind, she’ll become a powerful living bomb who can’t be defused. Sarah desperately tries to convince Sky that it’s still her choice whether or not to use that power… but when the Metalkind start arriving, what chance will anyone on Earth have?
