DUCKS IN SPACE! Fenton Crackshell - a.k.a. Gizmoduck - has to get out of town. Like, really out of town. After a mechanical miscue in his Gizmoduck gear leads to the destruction of a Duckburg bank, Uncle Scrooge reassigns him to the McDuck Moon Mines, where he can use his technical savvy to count rocks - and stay out of trouble! But when Scrooge and the boys pay a visit to his lunar holdings via rocket ship, the usually tranquil Moon is suddenly assaulted by alien invaders. These unfriendly space pirates pack a lot of firepower, which means that for once, Uncle Scrooge might be grateful for Gizmoduck's super-heroics - that is, if they all manage to survive!
