Plastic Man is shot out of the sky. Plastic Man quickly remolds himself into a raft. Despite the Flash providing propulsion, both he, and Plastic Man, are hit by German gunfire. The German's close in on the All-Star Squadron. Suddenly, the Green Lantern, the Marvel Family, Superman, and Wonder Woman attack the Germans. The All-Star Squadron just managed to get the Batsons, and Freeman, out of Nazi-occupied territory, freeing the Marvel Family from the spell of the Spear of Destiny. The battle over, the Batsons, Freeman, and the Marvel Family, all speak their magic words in unison, reuniting them, while simultaneously, returning them to Earth-"S".
