Liberty Belle and Johnny Quick are as surprised as anyone to learn that villains straight out of the comic-strips are attacking Metropolis en masse! But as they spend that day recruiting help from fellow team members of the All-Star Squadron, in between making plans for their impending nuptials, they find that Superman and Lois Lane already have the situation well in hand with a comic-strip team of their own!
