Synopsis:
Batman has several confrontations with the gang of a costumed crook known as the Masquerader. Several of Batman's costumes are damaged in the fights. Batman contacts his tailor Sam Tweed to make a new costume, which Robin picks up from police headquarters.

When Batman opens the box containing the costume he finds a second outfit belonging to the Masquerader inside. He calls Sam who claims that he was forced to make the costume at gunpoint. The Masquerader then shoots Sam.

Batman races to the tailor's shop. Sam tells Batman where the crook has gone. An ambulance then arrives to take him to the hospital. Batman goes to the location given to him only to discover it is a trap.

The Masquerader is actually Tweed himself. The new costume Batman receives is made of a restrictive material that shrinks when heated. An overhead heat lamp causes Batman to be crushed by his own costume. Batman triggers the sprinkler system. The water allows his costume to cool and expand again. He then defeats the Masquerader and removes the deadly costume.
