Plot
At one night in a casino with Roman Sionis, Gillian B. Loeb and Howard Branden, they are playing poker with an mysterious figure wearing a purple suit arriving. He called himself "just a nameless clown", and joined in with the poker game despite Sionis' dislike towards him. After halfway through the game, he left the casino and Branden discovered all of his playing cards are all Joker's. He panicked and one of them was knocked into his neck, slitting it and killing Branden. Loeb quickly called his police force and ambulances in an attempt to help Howard however he was dead and Sionis claimed the killer was the man who unexpectedly joined in with their poker game.

Bruce Wayne and Alfred Pennyworth discussed the mysterious murder but Wayne deduced there was something to do with the cards. He became Batman and took one of the Joker playing cards from the casino, discovering it was razor sharp unlike the other playing cards. On the news, Vicki Vale was on the scene questioning Captain James Gordon and even the casino manager who defended his company, not knowing why he died from the card. Sionis and Loeb had a private meeting together; but once Loeb had a drink from his beer, he began chuckling which angered Sionis. Loeb then started to laugh uncontrollably with his eyes starting to water and bulge, he then collapsed on the ground dead. Paramedics and police officers arrived and turned Loeb's corpse over, revealing a large, grotesque horrifying grin; scaring everyone. Batman eventually confronted Sionis and interrogated him on the murders, but Batman then deduced he isn't responsible and had Alfred give the police an anonymous tip to provide Sionis with police protection as they believed the killer would target him soon.

With the police in the same room with Black Mask, with one claiming that nobody will get past them. However one started to doubt him and began uncontrollably laughing, eventually ripping off his own face, revealing to be the mysterious killer. The police along with Black Mask were in shock, so it cut off-screen to the door with the cops starting to scream but screams turned into laughs. One officer managed to call for more backup, which alerted Batman. Batman, in the Batmobile, entered with all the officers dead with the same creepy grins as Loeb's corpse. Black Mask was also gone, causing Batman to deduce that his been kidnapped. Batman pursued them throughout the night to no effort but discovered a large Jack N' The Box which jumped up with a large sign saying "Boo!".
