Storyline
Mike Mahoney stands up Sky Gal and that worries her because he's not a stand-up kind of guy. She flies off looking for him and sees a message from him in the Secret Valley. It is up to her to save him from the cannibals and Japanese soldiers.
Story Notes
Only change in the reprint is the change in the feature heading from Sky Girl to Sky Gal, the addition of a title and the printing in black and white.
