A gigantic dam built to bridge the Bering Strait keeps collapsing. Dr Elefun knows that the one scientist who could save the project is Angus Muse, who has sworn off contact with the outside world. He lives in the Alps with his granddaughter Angelica. When her parents were killed by the robots of Mr Vile, Dr Muse swore off all contact with machines, ESPECIALLY ROBOTS. It's up to Astroboy (disguised as a human boy named, oddly enough, Aster Boynton) to change his mind.
