The showing was going on when Angus Ferguson saw the crimefighting gang enter it.
"Aye. The Caped Crusader and the Boy Wonder" he said.
Then he shook hands with each of the Warriors and said "And of course their friends. The Red Warrior... the Green Warrior... and the Blue Warrior. Well, it's good to have you here. Help yourself to a wee deoch an doris".
Then he said something in Scottish while the Warriors accepted his invitation.
"Thank you, Mr Ferguson, but we'd just like to browse a bit" said Batman.
"Browse? Aye, browse. Browse to the content of your stout heart" said Ferguson.
Batman and Robin then approached a rare looking doorway.
"It's a docket door" said Robin.
"Gaelic for stirrup cup, Robin. A drink usually taken on parting" said Batman.
"You think he's trying to get rid of us?" said Robin.
"I think we should try to act as casual as possible, old chum" said Batman.
The duo then found a gigantic silver key on display.
"Hmm. A rare acquisition" said Batman.
The label under the key said "the key to the Bastille cell block in which the man in the iron mask was imprisoned".
"How could Mr Ferguson have gotten that?" said Robin.
"A golden key opens every lock, Robin" said Batman.
Then he saw a curtained doorway with a sign that said "The Jeweled Key of Kaincardine".
"Warriors. Look" said Robin.
The kids looked at the sign themselves.
"Gawrsh. That must be the key Joker is after" said Sam.
"Shall we?" said Batman.
The guys entered through the curtained doorway.
"Holy keyhole!" Robin gasped.
He was looking at the golden key of Kaincardine which was displayed on a picture frame.
There were emeralds, rubies, fire opals and sapphires all over it.
"If there's any dirty work afoot, you can be sure that this key is the hoped-for target" said Batman.
"It must be worth a fortune" said Robin.
The Joker burst through more curtains and said "More than a fortune, Boy Wonder! It's priceless. And you're right, Batman. My target is the jeweled key of Kaincardine".
"Which, luckily, we'll prevent you from obtaining!" Calvin snapped.
"Oh, I wonder, clever Calvin. I anticipated your presence here today. And I believe my newest invention will render you helpless while I transfer ownership of the priceless jeweled key" the Joker babbled.
He used his magic box to put the gang in a daze while he stole the key.
The guys got their senses back after the Joker left.
"Are you alright, Robin?" said Batman.
"I think so, Batman" said Robin.
"Warriors. You alright?" said Calvin.
"I'm good, Cal" said Charles Wallace.
"Sam, baby... are you okay?" said Robin holding Sam's shoulders.
"Uh-huh. I'm fine. What happened?" said Sam.
"I'm not sure" said Robin.
"Batman! They key's gone!" said Charles Wallace.
"It certainly is gone" said Batman.
