Clark Kent and Jimmy Olsen, on duty as reporters, visit a club that is devoted to thumbing its collective nose at any and all superstitions. Members must walk under a ladder after entering the rented meeting house. Pins are left all over the floor, and members are forbidden to pick any up. The chairman calls the meetings to order by breaking a mirror. Their mascot, of course, is a black cat. But bad things begin to befall members. The floor nearly caves in during Kent and Olsen's visit. Later, a member's chemical company catches fire. None of these things are put down to bad luck: they are clearly the work of a saboteur. Suspicion falls on the meeting house's raving, superstitious landlord. It's up to Superman, however, to find the true culprit.
