The Justice Ducks are each defeated and captured by the Fearsome Five. Darkwing rushes to the rescue, and the five heroes join in battle against the five villains, with the ultimate victors deciding the fate of the whole city.

Honker and Gosalyn track down a set of dinosaur footprints, and are led to the nefarious Dr. Fossil, duck turned dinosaur. With his de-evolution ray and the aid of a passing comet, Fossil plans to end the current life on the planet to give dinosaurs a second chance.
