Synopsis:
Ralph Dibny visits a museum featuring replicas of real treasures from around the world. Suddenly he and other visitors are rushed out of the exhibit after the owner and tour guide acts shocked that the crown jewels of England are fake. Suspicious, Ralph follows the owner to an underworld location where he meets a counterfeiter named Lietag. Ralph apprehends them all.

He later explains to Sue that Lietag created a fake set of jewels and the museum owner swapped them for the real ones. The real ones were then hidden in plain sight in the museum. However Lietag pulled a double-cross using a second set of fakes. The owner discovered the fakes and went to confront Lietag when Ralph intervened.
