In a daring bid to unravel the mystery of vanished engineering teams in the Andes, Editor Perry White, Lois Lane, and Clark Kent take to the skies in a powerful stratoplane. But an urgent call from Washington halts Kent's journey, beckoning him to a puzzling assignment away from the action. As the plane ascends, eerie flute-like sounds pierce the cabin, and a perilous oxygen shortage grips the crew. Will Superman's absence spell doom for his friends, or can he navigate the perils of duty and distance to come to their rescue?
