Ep 42. Joker's Wild

An enraged Joker breaks out of Arkham Asylum when he learns billionaire developer Cameron Kaiser has built a gambling casino, Joker's Wild, exploiting the evil clown's likeness. Batman is also infuriated, knowing the Joker will destroy the casino and everyone in it to avenge his wounded pride. This is all part of Kaiser's plan, for he's counting on collecting a fortune in insurance money when the Joker blows the place up. Unpredictable as always, the Joker later decides to kill Kaiser and run the casino himself. Batman's last-minute intervention saves Kaiser's life and sends the Joker back to Arkham.
