Hugh Rankin almost gets himself killed trying to stop the Make-Up Man on his own, so Batman and Robin take over.
Tipped off by private investigator Hugh Ranking (who has been trying to get into the Mystery Analysts of Gotham club) Batman and Robin attempt to stop a hiest at the Jewel Mart, but find that the robbers are almost inhuman in their strength and mannerisms. As more hiests are planned, Hugh learns that the whole thing is being orchistrated by a criminal calling himself Make-Up Man, who is using anamatronic machines that look like people to do his robberies, but is captured by his thugs.
When Batman and Robin track down the clues to Make-Up Man's hide out, they end up fighting his constructs, and a giant mask, the Dynamic Duo manage to capture Make-Up Man and rescue Hugh. Hugh apologizes for his impulsiveness telling Batman that he only wanted to be inducted into the Mystery Analysts, Batman tells him that one day he'll be admitted to the group if he works at it.
